193	= How to protect sites from spam bots without CAPTCHA? =
194	- The most popular anti spam 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.
195	- Sometimes CAPTCHA reminds us of the doodles of a two year old child. For users
196	- with vision problems CAPTCHA is an insurmountable obstacle. Users hate
197	- captcha. Captcha for users means "hate". Unreadable CAPTCHA stops about 80% of
198	- site visitors. After 2 failed attempts to decipher CAPTCHA 95% of visitors
199	- reject further attempts. At the sight of CAPTCHA and after input errors, many
200	- visitors leave the resource. Thus, CAPTCHA helps to protect the resource spam both from bots and visitors. CAPTCHA is not a panacea from spam. Doubts concerning the Need for CAPTCHA?

203
204	You do not have to work in IT to know what spam is. Besides piles of unwanted email, there are spam bots, or special software programs designed to act as human website visitors that post unwelcome messages over the Internet to advertise dubious services. More often than not spam messages do not even make sense. Similar to bacteria and virus mutations developing antibiotic resistance, spam bots are becoming more resilient in penetrating Internet firewalls and security layers.

206	= CleanTalk's features =
207	Anti-Spam by CleanTalk is one of the fastest plugins that allows you to lower the server load. One of the important parameters for each webmaster is the speed of the site, so we make sure that our plugin consumes as few server resources as possible. The Cloud Service provides the advantage: all data processing takes place in the Cloud.
208
209	- CleanTalk team has developed unique anti spam algorithms to assess visitors'
210	- behavior. CleanTalk analyzes user behavior and the parameters of the filled
211	- forms. Our anti-spam module, being installed in your website, sends the
212	- behavior parameters of either a visitor or a spam bot. When these parameters
213	- are estimated, the anti spam service makes a decision � to post a message or to define it as spam and reject it. Based on these checks, the service forms its own list of email addresses used by spam bots.
214
215	The registrations of visitors are being checked in a similar manner. The service adds to the blacklist not just email addresses, but also IP addresses and domains of websites that promote themselves through spam mailing. All of this happens automatically and requires no action from the administration of the website. In 2.5 million queries the service makes a mistake in 40-45 cases, i.e. CleanTalk detects spam with 99.9982% accuracy. We constantly monitor these errors and make adjustments to our algorithms. Even with this exceptional accuracy our team is aiming to improve the figures over time.
216
217	- All-in-one. CleanTalk protects form spam all forms instantaneously � comments, registrations, feedback, contacts. No need to install additional plugins for each form. You save resources and increase performance of your website.
218
219	- Spam attacks log. Anti-Spam by CleanTalk records all filtered comments, registrations and other spam attacks in the �Log of spam attacks� and stores the data in the log for up to 45 days. Using the log, you can ensure reliable protection of your website from spam and experience no false/positive filtering.
220
221	- With the help of anti-spam by CleanTalk you can check existing comments and
222	- users, to find and quickly delete spam comments at once. This allows
223	- administrators of websites to automatically check and identify spam bots,
224	- comments and users, which were not detected by conventional anti-spam tools.
225	- The existing comments and users checking process is performed in a database of
226	- the nearly 2 million identified spam bots. Detailed spam stats allows CleanTalk customers to fully control it.
227
228	- CleanTalk has an advanced option �SpamFireWall�. This option allows you to block the most active spam bots before they get access to your website. It unloads you website pages when an attempt attack was made, so your web server won't run unnecessary scripts on these pages. Also it prevents any scanning of website pages by spam bots. Subsequently SpamFireWall significantly reduces your webserver load. SpamFireWall can mitigate HTTP/HTTPS DDoS attacks. When an intruder makes GET requests to attack your website, SpamFireWall will block requests from bad IP addresses. Your website gives the intruder a special page with a description of DDoS rejection instead of the website pages. SpamFireWall can help to reduce the CPU usage of your server because of this reason.
