We have developed an anti-spam extension for XF 2 that would provide maximum protection from spam and you can provide for your visitors a simple and convenient form of posts/registrations without annoying CAPTCHAs and puzzles. Used to detect spam multistage test that allows us to block up to 100% of spambots.
CleanTalk has got an advanced option "Spam FireWall", this option allows blocking of the most active spambots before they get access to a website. It prevents the loading of pages of the website by spambots, so your web server doesn't need to perform all scripts on these pages. Also, it prevents the scanning of pages of the website spambots. Therefore Spam FireWall significantly can reduce the load on your web server.
Spam FireWall also makes CleanTalk the two-step protection from spambots. Spam FireWall is the first step and it blocks the most active spambots, CleanTalk Anti-Spam is the second step and it checks all other requests on the website at the moment before submitting comments/registers and etc.
Low false/positive rate
This extension uses multiple anti-spam tests to filter spambots with a lower false/positive rates as possible. Multiple anti-spam tests avoid false/positive blocks for real website visitors even if one of the tests failed.
Spam attacks log
Service CleanTalk (this hook is a client application for CleanTalk anti-spam service) records all filtered comments, registration and other spam attacks in the "Log of spam attacks" and stores the data in the log up to 45 days. Using the log, you can ensure reliable protection of your website from spam and no false/positive filtering.
Real-Time Email Address Existence Validation
It is very important to be sure that the user used his real email address. Spambots very often use fake email addresses, i.e. which addresses do not exist. Non-existing email addresses also entail several other problems for website owners:
- You can never contact them by email,
- The client will never receive any notifications from you (account activation letter, password recovery, email distribution, notifications, etc.),
- If you use email marketing for your clients, then a large number of nonexistent emails in the mailing list may result in your IP address being added to various blacklists of email servers.
Blocking disposable & temporary emails
Block fake and suspicious users with disposable & temporary emails to improve email delivery. So, it also prevents malicious activity, spam bots, and internet trolls.
Automatically block comments and registrations from your private black IP/email address list. This option helps to strengthen the protection from a manual spam or block unwanted comments from users. You can add not only the certain IP addresses but also a separate subnet to your personal blacklist.
Blocking users by country
Automatically block comments and registrations from the countries you have set a ban for. This option is useful in cases of manual spam protection and for protection enhancement. If your site is not intended for an international audience and you do not expect comments/users from other countries.
Blocking comments by "stop words"
You can block comments which contain "stop words" to enhance spam filtering and messages with obscene words blocking. You can add particular words or phrases.
