Bad Behavior is a set of PHP scripts that is designed to keep your blog or forum clean from spam by taking a much different approach than typical solutions. While I could go into a big explanation, you can read all about it here
That said, Drupal 7 is available for download, but the Drupal 6 Bad Behavior module has not yet been ported to Drupal 7. These instructions will help you get a very crude installation of Bad Behavior protecting your Drupal 7 site, albeit in the “no logging” mode, which is not the preferred method. If you’re familiar with Drupal 7 enough to attempt a port, I would ask that you please visit the Drupal 6 module and contact the developer. The Drupal community would greatly appreciate it.
These instructions are based on the Bad Behavior Porting Guide.
First, download Bad Behavior from http://bad-behavior.ioerror.us/download/
When you unzip it, you should have a folder called bad-bahavior.
Upload that folder somewhere to your web root, so that bad-behavior-generic.php is accessible as http://example.com/bad-behavior/bad-behavior-generic.php (These are sample instructions only, advanced users are encouraged to place the scripts wherever they like.)
Locate the following line:
'httpbl_key' => '',
Input your http:BL API key from Project Honey Pot. If your API key is ‘exampleAPIkey’, you’ll have this:
'httpbl_key' => 'exampleAPIkey',
edit drupal index.php
Right below the opening require_once(“bad-behavior/bad-behavior-generic.php”);
