  == Frequently Asked Questions ==
213
- = Does the plugin protect against brute force, DoS attacks as well as against spam attacks? =
214
- No, it doesn't. Anti-spam by CleanTalk **is anti-spam solution** for comments, registrations and other other forms on a website only. The plugin saves your time in managing spam problems, but doesn't protect against any security issues.
215
 
216
  = Is the anti-spam protection safe for mobile visitors? =
217
- Yes, it does is. The plugin doesn't block mobile visitors as well as desktop website visitors. It uses several independent anti-spam tests to decrease the number of false outcomes and to have as low false-positive rate as possible. Multiple anti-spam tests help to avoid false/positive blocks for real website visitors even if one of the tests failed.
218
 
219
  = What does the plugin do with spam comments? =
220
- Spam comments are being moved to SPAM folder or you can set the option to ban spam comments silently.
221
 
222
  = How does the plugin stop spam? =
223
- The plugin uses several simple tests to stop spammers.
224
 
225
- 1. JavaScript anti-spam test. 99% of spam bots don't have full JavaScript functions support. So, the plugin has the code which can be run by normal visitor and can't by run by the spam bot.
226
- 1. Email, IP, domain spam activity list entries check. The plugin online uses spam activity database online at cleantalk.org, consisting of more than 20 billion spam activity records from IPs, Email, Domains and ASN. If the sender's IP or Email is in the database, the sender gets some spam scores. To reduce false/positive rate the plugin not only uses the blacklist test to ban spammers. The sender will be banned when and only when multiple spam tests have been failed.
227
- 1. Comment submit time. Spam bots usually submit the info immediately after the page has been loaded, this happens because spam bots don't actually fill the web form, they send $_POST data to the blog only. The normal visitor sends the data after several seconds or minutes.
228
 
229
- = Will this anti-spam plugin protect my theme? =
230
  Yes, it will. The Anti-spam by CleanTalk is compatible with any WordPress theme.

242
- Sure, you can use CleanTalk with Akismet. In this case you will probably have higher false/positive rate (when legitimate comments/signups are being denied), but you will have stronger antispam protection at website.

  Yes, you can. The plugin has the option to test all pending comments via database of <a href="https://cleantalk.org/blacklists">spam active IP/Email</a>, found spam comments will be moved to Trash folder.
249
 
250
  = How does the plugin find spam in pending comments or registered accounts? =
251
- The plugin checks all non-spam comments in the blacklist database and shows your those senders who have spam activity on other websites.
252
- There are some differences between blacklist database and API to protect you from spam bot registrations/comments online. Blacklists show all history of spam activity, but our API (which is used in spam tests) relies on other parameters, too: last day of activity, number of spam attacks during the last days etc. This mechanisms help us to reduce number of false/outcomes. So, there is nothing strange, if some emails/IPs are not found by bulk comments/accounts test.
253
 
254
- To check comments please go here,
255
  > WordPress console -> Comments -> Find spam comments
256
 
257
- To check users please go here,
258
  > WordPress console -> Users -> Find spam users
259
 
260
- = Should I use another anti-spam tools (Captcha, reCaptcha and etc.)? =
261
- CleanTalk stops up to 99.998% of spam bots, so you can disable other anti-spam plugins (especially CAPTCHA like anti-spam plugins). In some cases several anti-spam plugins can conflict, so it will be better use just one plugin.
262
 
263
- = Is the plugin WordPress MultiUser (WPMU or WordPress network) compatible? =
264
- The plugin is WordPress MultiUser (WPMU or WordPress network) compatible. Each blog in multisite environment has individual anti-spam options for spam bots protection.
265
 
266
- = After installation I noticed in the statistics that the number of spam attacks increased =
267
  There are a few reasons for this:
268
 
269
  * With the indexing of your web-site by the search systems, appearance of external links and better search results position, your web-site attracts more and more spambots.
270
  * Non-transparent protection systems like CAPTCHA or question/answer, that don't have spam attacks statistics, don't let you see the whole picture, or the picture is incomplete.
271
- * Counting methods for spam attacks and spam bots are different for different systems, which explains the diversity. We seek to provide detailed statistics.
272
 
273
  = Why my dummy "spam" comment passed to the WordPress? =
274
- The plugin has several options to detect spam bots and humans. If you just post spammy text like this,
275
 
276
  "I want to sell something", "Buy something here.." and etc
277
 
278
- The comments will be passed, becuase the plugin detect sender as a human. So, use special email *stop_email@example.com* to test anti-spam or wait a few days to see how the plugin works.
279
 
280
  = Is it free or paid? =
281
- The plugin is free. But the plugin uses CleanTalk cloud service to filter spam bots. You have to register an account and you have free trial to test anti-spam for comments, registrations, bookings, contacts or orders. When the trial (on CleanTalk account) is finished, you can renew the subscription for 1 year or deactivate anti-spam plugin.
282
 
283
  = Can I use CleanTalk with cache plugins? =
284
- Anti-spam by CleanTalk doesn't use static HTML code into templates, so all anti-spam functions works correctly with any WordPress cache plugins.
285
 
286
- = Does the plugin protects against spam bots at forms with third-party services? =
287
- Yes, it does. Plugin protects web-forms on your websites which are send data to third-party servers (like MailChimp). To enable this protection set option 'Protect external forms' in plugin settings.
288
 
289
  = Does CleanTalk compatible with Cloudflare? =
290
- CleanTalk is fully compatible with CloudFlare. Service doesn't filter CloudFlares IP's (AS13335) over blacklists database, so in this way plugin/service filters spam bots uses other anti spam tests.

215
  == Frequently Asked Questions ==
216
+ = Does the plugin protect from brute force, DoS attacks and spam attacks? =
217
+ Yes, it does. Please turn the option 'SpamFireWall' on in the plugin settings to protect your website from DoS/DDoS, XML-RPC attacks.
218
 
219
  = Is the anti-spam protection safe for mobile visitors? =
220
+ Yes, it is. The plugin doesn't block mobile visitors as well as desktop website visitors. It uses several independent anti-spam tests to decrease the number of false outcomes and to have as low false-positive rate as possible. Multiple anti-spam tests help to avoid false/positive blocks for real website visitors even if one of the tests failed.
221
 
222
  = What does the plugin do with spam comments? =
223
+ Spam comments are being moved to SPAM folder by default or you can set the option to ban spam comments silently.
224
 
225
  = How does the plugin stop spam? =
226
+ The plugin uses several simple tests to stop spammers:
227
 
228
+ 1. **JavaScript anti-spam test.** 99% of spam bots don't have full JavaScript functions support. So, the plugin has the code which can be run by normal visitor and can't be run by the spam bot.
229
+ 1. **Email, IP, domain spam activity list entries check.** The plugin uses spam activity database online at cleantalk.org, consisting of more than 20 billion spam activity records of IPs, Emails, Domains and ASN. If the sender's IP or Email is in the database, the sender gets some spam scores. To reduce false/positive rate the plugin not only uses the blacklist test to ban spammers, the sender will be banned when and only when multiple spam tests have been failed.
230
+ 1. **Comment submit time.** Spam bots usually submit the info immediately after the page has been loaded, this happens because spam bots don't actually fill the web form, they just send $_POST data to the blog. The normal visitor sends the data after several seconds or minutes.
231
 
232
+ = Will the anti-spam plugin protect my theme? =
233
  Yes, it will. The Anti-spam by CleanTalk is compatible with any WordPress theme.
234
 
235
  = How can I test the anti-spam protection? =
242
  The plugin passes pingbacks without any checks by default. All trackbacks will be blocked if the sender had spam activity.
243
 
244
  = Can I use CleanTalk with Akismet? =
245
+ Sure, you can use CleanTalk with Akismet. In this case you will probably have higher false/positive rate (when legitimate comments/signups are being denied), but you will have stronger antispam protection on your website.
246
 
247
  = Is CleanTalk better than Akismet? =
248
  Please look at this features comparison here https://cleantalk.org/cleantalk-vs-akismet
251
  Yes, you can. The plugin has the option to test all pending comments via database of <a href="https://cleantalk.org/blacklists">spam active IP/Email</a>, found spam comments will be moved to Trash folder.
252
 
253
  = How does the plugin find spam in pending comments or registered accounts? =
254
+ The plugin checks all non-spam comments in the blacklist database and shows you those senders who have spam activity on other websites.
255
+ There are some differences between blacklist database and API to protect you from spam bot registrations/comments online. Blacklists show all history of spam activity, but our API (which is used in spam tests) relies on other parameters too: last day of activity, number of spam attacks during the last days etc. These mechanisms help us to reduce the number of false outcomes. So, there is nothing strange, if some emails/IPs are not found by bulk comments/accounts test.
256
 
257
+ To check comments please go here:
258
  > WordPress console -> Comments -> Find spam comments
259
 
260
+ To check users please go here:
261
  > WordPress console -> Users -> Find spam users
262
 
263
+ = Should I use other anti-spam tools (Captcha, reCaptcha and etc.)? =
264
+ CleanTalk stops up to 99.998% of spam bots, so you can disable other anti-spam plugins (especially CAPTCHA-type anti-spam plugins). In some cases several anti-spam plugins could conflict with each other, so it would be better to use just one plugin.
265
 
266
+ = Is the plugin compatible with WordPress MultiUser (WPMU or WordPress network)? =
267
+ Yes, the plugin is compatible with WordPress MultiUser. Each blog in multisite environment has individual anti-spam options for the protection from spam bots.
268
 
269
+ = After the installation I noticed that the number of spam attacks has been increased in the statistics =
270
  There are a few reasons for this:
271
 
272
  * With the indexing of your web-site by the search systems, appearance of external links and better search results position, your web-site attracts more and more spambots.
273
  * Non-transparent protection systems like CAPTCHA or question/answer, that don't have spam attacks statistics, don't let you see the whole picture, or the picture is incomplete.
274
+ * Counting methods for spam attacks and spam bots are different for different systems, thus the diversity appears. We seek to provide detailed statistics.
275
 
276
  = Why my dummy "spam" comment passed to the WordPress? =
277
+ The plugin has several options to detect spam bots and humans. If you just post spammy text like this:
278
 
279
  "I want to sell something", "Buy something here.." and etc
280
 
281
+ the comments will be passed, because the plugin detects sender as a human. So, use special email *stop_email@example.com* to test the anti-spam functionality or wait a few days to see how the plugin works.
282
 
283
  = Is it free or paid? =
284
+ The plugin is free. But the plugin uses CleanTalk cloud service to filter spam bots. You have to register an account and then you will receive a free trial to test anti-spam for comments, registrations, bookings, contacts or orders. When the trial (on CleanTalk account) is finished, you can renew the subscription for 1 year or deactivate anti-spam plugin.
285
 
286
  = Can I use CleanTalk with cache plugins? =
287
+ Anti-spam by CleanTalk doesn't use static HTML code in its templates, so all anti-spam functions work correctly with any WordPress cache plugins.
288
 
289
+ = Does the plugin protect from spam bots if I use forms with third-party services? =
290
+ Yes, it does. Plugin protects web-forms on your websites which send data to third-party servers (like MailChimp). To enable this protection set the option 'Protect external forms' in the plugin settings.
291
 
292
  = Does CleanTalk compatible with Cloudflare? =
293
+ CleanTalk is fully compatible with CloudFlare. Service doesn't filter CloudFlares IP's (AS13335) through blacklists database, so in this case plugin/service filters spam bots using other anti-spam tests.
294
 
295
+ = Is CleanTalk compatible with a content delivery network (CDN)? =
296
+ Yes, it is. CleanTalk works with any CDN system, i.e. CloudFlare, MaxCDN, Akamai.
297
 
298
  = Can I use CleanTalk functionality in my plugins? =
299
  Yes, you can. Just use following snippet:
312
  * $res['allow'] - is request allowed (1) or not (0)
313
  * $res['comment'] - comment for our server's decision.
314
 
315
+ = I see two loads of script cleantalk_nocache.js. Why do you use it twice? =
316
+ This script is used for AJAX JavaScript checking. Different themes use different mechanisms of loading, so we use two methods for loading our script. If you absolutely know what you are doing, you can switch one of the methods off by defining constants in your wp-config.php file:
317
 
318
  define('CLEANTALK_AJAX_USE_BUFFER', false); //false - don't use output buffering to include AJAX script, true - use it
319
 
322
  define('CLEANTALK_AJAX_USE_FOOTER_HEADER', false); //false - don't use wp_footer() and wp_header() for including AJAX script, true - use it
323
 
324
  = Can I add exclusions for some pages of my site? =
325
+ Yes, you can. Add this string in your wp-config.php file before defining database constants:
326
 
327
  $cleantalk_url_exclusions = Array('url1', 'url2', 'url3');
328
 
329
+ Now, all pages containing strings 'url1', 'url2', or 'url3' will be excluded from anti-spam checking. Remember, that this option will not be applied in registration and comment checking — they are always protected from spam.
330
 
331
+ = Can I not send my personal data to CleanTalk servers? =
332
+ Yes, you can exclude your data. Add this string in your wp-config.php file before defining database constants:
333
 
334
  $cleantalk_key_exclusions = Array('key1', 'key2', 'key3');
335
 
336
+ Now all fields in your submissions with the keys named 'key1', 'key2' or 'key3' will be excluded from spam checking.
337
 
338
  = How to test SpamFireWall? =
339
  Use special IP 10.10.10.10 in URL to test SpamFireWall. For example,
347
 
348
  Now, all subsites will have this access key.
349
 
350
+ = Why is CleanTalk faster and more reliable than stand-alone solutions? =
351
+ All anti-spam checks are held in the cloud and don't overload the web server. The cloud solutions have a huge advantage since the parameters are being compared with information from more than 100,000 websites.
352
 
353
+ = I see a lot of blocked messages with the reason "Forbidden. Please enable JavaScript. Spam sender name." in my logs =
354
+ A lot of spam bots can't perform JavaScript code, so it is one of the important checks and most of the spam bots will be blocked with the reason **"Forbidden. Please enable JavaScript. Spam sender name."** All browsers can perform JS code, so real visitors won't be blocked.
355
 
356
+ If you or some of your visitors have the error **"Forbidden. Enable JavaScript."** please check JavaScript support in your browser and do this JavaScript test at this page: https://cleantalk.org/checkout-javascript-support.
357
 
358
+ If you think that there is something wrong in the messages blocking, let us know about it. Please submit a support request here: https://cleantalk.org/my/support.
359
 
360
  = Does the plugin work with Varnish? =
361
+ CleanTalk works with Varnish, it protects WordPress against spam, but by default the plugin generates a few cookies for the protection from spam bots and it also disables Varnish cache on pages where CleanTalk's cookies have been stored. To get rid of the issue with cache turn off the option 'Set cookies' in the plugin settings.
362
 
363
  WordPress console -> Settings -> CleanTalk -> Advanced settings
364
 
365
+ Now the plugin will protect WordPress comments, registrations and most of popular contact forms, but will not protect some of rarely used contact forms.
366
 
367
  = Does the anti-spam plugin work with Accelerated Mobile Pages (AMP)? =
368
+ Yes, it does. But you have to turn off the option 'Use AJAX for JavaScript check' in Advanced settigns of the plugin to be fully compatible with Accelerated Mobile Pages.
369
 
370
  = How to close renewal or trial notice in the WordPress backend? =
371
+ To close the notice please save the plugin settings again or it will be closed automatically within 60 minutes after the renewal.
