Attempts to prevent automated SPAM by requiring visitors to answer a question of your choosing in order for their comment to be accepted. Presumably, spambots will be unable to correctly answer this question and so comments they attempt to post will be rejected.
Only regular comments from non-logged-in users are filtered. Pingbacks, trackbacks and authenticated users will not be prompted to answer the verification question.

Super Simple SPAM Stopper

Prevents automated SPAM by requiring visitors to answer a question of your choosing (plaintext or regex).

IceCaptcha

The new generation “IceCaptcha” plugin.
The new security system presupposes clicking on the circle of a particular color instead of entering numbers or other redundant actions. It is done instead of clicking on the button, i.e. no spare action is required!
As for the bots or foreign captcha entering services, the task practically can’t be solved as the circle is drawn randomly in various places, it is of random color and the background (the picture itself) is also different every time. The click spot coordinates are encrypted and sent to the server where the checkup is performed. This all brings us to the fact that there is no chance of switching or calculating the correct result for any third party software.
You can use our captcha for: • Registering new users • Authenticating users • Commenting anti spam security

This is the new generation IceCaptcha plugin. The Anti-Spam security system misses no bots and does not disturb a human being.
