Kill Malicious Traffic With Bad Behaviour Plugin

The second version of one of the more popular wordpress plugins, Bad Behaviour, has been recently released.

Bad Behaviour identifies many malicious activities and not limited to spamming alone.

Bad Behavior, conceived in 2005 as a fingerprinting method for HTTP requests, has proven, as one user called it, “shockingly effective” at identifying and blocking malicious activity, including blog/wiki spam, e-mail address harvesting, automated cracking attempts, and more. It does all of this looking only at the HTTP request headers; for POST data, the content of the spam is not analyzed at all.

I might give this a try one of these days.
