Bad Behavior Integration
Mod Version: 4.x, by SemperFideles

This is a simple integration of the https://www.bad-behavior.ioerror.us/. 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

Thanks for the link SemperFi!

For me, I was able to get Bad Behavior running to a certain extent on my VB install. They provide a small bit of direction on this page:
https://www.bad-behavior.ioerror.us/documentation/porting-guide/

So if you wanted to run it in a degraded mode (no logging), one can simply upload the files onto the site root, then create a new plugin with these settings:
Hook Location: global_start
Plugin PHP Code: require_once ("../bad-behavior-generic.php");

Again, there's no logging, but I've had great success with mine. Spambot registrations are down to a trickle, if not nearly zero.

There's also instructions in the Porting Guide link above for those that want a full install and know how to create the appropriate hooks.

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 https://www.bad-behavior.ioerror.us/download
