phpBB2 Mod: SFS Anti-Spam Registration

The SFS Anti-Spam Registration Mod is a modification for phpBB2 (tested 2.0.18 – 2.0.23) that interfaces with the stopforumspam.com API to verify user details during registration.  If the API returns any hits from the blacklist on the user IP, email address, or username, registration is prevented.  This mod also provides automatic code adjustment for both php4’s domxml and php5’s dom, so it is compatible with servers running either version of php.
