Math Comment Spam Protection

This plugin asks the visitor making the comment to answer a simple math question. This is intended to prove that the visitor is a human being and not a spam robot.

Example of such question:

This plugin does not require JavaScript or cookies. It uses a special encryption function; the result of the question is being passed via a hidden field. The result is being compared with the value entered by the visitor – after encrypting this value as well.

For details, installation instructions and download visit Math Comment Spam Protection Plugin.
