Bad Behavior Integration
 

This is a simple integration of the Bad Behavior Script. Bad Behavior is a PHP-based solution for blocking link spam and the robots which deliver it. Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site?s load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.

I use this in conjunction with the Project Honeypot addon and the vBStopForumSpam addon. The three ought to be considered a layered defense at reducing spam and other unwanted traffic to your site that simply consumes resources.

*NOTE: The Project Honeypot addon has now added Bad Behavior implementation, which makes this implementation superfluous if you are using that plugin. Do not install if you have the latest version of the Project Honeypot.

I don't want to take credit for implementation as the idea originated with this thread

This is a simple implementation of the script and it will work but it will not provide any logging. I'll leave it to others who know more about how to improve this to enable logging.

Installation instructions:

1. Extract the contents of the zip file and upload the contents of the upload folder to your forum root. (Note: Latest stable version of bad behaviour can always be found here
2. Install Product.

Updates:
01/21/2010: Created Product file in lieu of plugin code to make it easier to install/uninstall.
01/22/2010: Added Bad Behaviour files for convenience.
01/24/2010: Simplified installation and included the php code within the plugin for the generic implementation of Bad Behavior per simonhind's suggestion below.
01/09/2011: Updated BadBeheavior.zip and included bad-behaviour files to 2.0.39
Added BadBehavior2.1.8.zip to include 2.1.8 developmental version

Very interesting - tagged. I'd like to read some firsthand experiences with using it on vBulletin forums before I install.

Tagged until I update to vB4 (tomorrow probably). Thanks much!

Does this work on vb 3.8.3 ?

So it's just the bad-behavior folder you up to the forum root and not the rest of the stuff?

Yes.
When you download the latest zip file it contains a bad-behaviour folder with php files in it as well as another bad-behaviour folder.

Upload the entire directory and file structur from the zip file.

Will be trying this today, Hopefully it will stop the likes of xrumer etc too . Since upgrading to VB4 ive suffered alot with link spam since the "CYB- advanced permissions based on post count" hasnt been released yet

Please let me know how it works out. The instructions for integrating with PHP based scripts is pretty straightforward but I'd love to hear back from people that it is actually cutting down on link spam. I'm hoping somebody will assist me in figuring out how to integrate logging because that is beyond my programming skills as I have little time to dedicate.

Do any big boards or high traffic boards run this? If yes, was any negative performance hit experienced?
