Three Strikes and You’re Out examines your Bad Behavior logs and your WordPress 
spam queue and closes comments on all blog entries across the board to IP 
addresses that have reported three or more attempts at mischief over the past 
seven days.
It also has an additional logging feature and an API that allows other plugins 
to register certain events as being mischievous.
<h3>Configuration</h3>
By default, Three Strikes and You’re Out closes comments right across the board 
on your blog to any IP address that has attempted any mischief three or more 
times in the past week. You can change these by editing the two defined 
constants at the top of the plugin file, just below the copyright notice. There 
are three such defines:
<ul>
<li><code>THREE_STRIKES_LIMIT</code> is the number of bad hits at which to block comments.</li>
<li><code>THREE_STRIKES_TIMEOUT</code> is the time in seconds after which bad hits are no 
longer considered.</li>
<li><code>THREE_STRIKES_BB_STRICT</code> indicates that you should consider any “strict” 
events recorded in the Bad Behavior log. These are events that are blocked when 
Bad Behavior is using the “strict checking” option, but would be ignored 
otherwise.</li>
</ul>
<h3>The Three Strikes API</h3>
This plugin includes a number of hooks that allow other plugins to communicate 
with it. These are implemented as actions and filters, so if Three Strikes is 
not installed, your plugin will continue to function.

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.
Privacy Note: This plugin does not call home or communicate with any external servers or services. All processing is done locally within your WordPress site.

Super Simple SPAM Stopper

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