This plugin rejects outright any comments that contain either (a) BBCode 
[url=…] tags or (b) more than a predefined number of hyperlinks. As comments 
of this nature are almost exclusively spam, this should cut down drastically on 
the amount of detritus that Akismet has to deal with, making it easier to check 
for false positives in your spam queue.
<h3>Configuration</h3>
The default settings enforce a limit of two hyperlinks per comment. 
To change this, edit the number in the line just below the copyright notice 
which says:
<pre><code>define('MAX_HYPERLINKS', 2);
</code></pre>
If you set it to zero, it will not allow any hyperlinks. To allow unlimited 
hyperlinks and only block BBCode, comment out this line.

Link Limits

Rejects comments that contain BBCode or too many hyperlinks.

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.
