  = How to protect sites from spam bots without CAPTCHA? =
140
  The most popular method is CAPTCHA - the annoying picture with curved and sloping symbols, which are presented to the visitor to decipher and fill in. It is supposed that spam bots won't discern these CAPTCHA, but a visitor will. CAPTCHA provokes great irritation, but if the visitor wants to comment, he has to fill in these symbols time after time, making mistakes and starting once again.
275
  = Does the plugin protects against spam bots at forms with third-party services? =
276
  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.
277
 
278
+ = Does CleanTalk compatible with Cloudflare? =
279
+ 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.
280
+
281
+ = Does CleanTalk compatible with a content delivery network (CDN)? =
282
+ Yes, it does. CleanTalk works with any CDN system, i.e. CloudFlare, MaxCDN, Akamai.
