What it does: This modification queries the stopforumspam.com database with the IP address and email of the user registering. If the IP address or email is found in the database, the user will get an error message and the registration process will be stopped. What you need: You'll need file_get_contents or CURL on your server for this to work. If one does not exist, it will try to use the other. Install: Just import the product in the Admin CP. Notes: If you want to customize the error messages, they are named "spammer_ip" and "spammer_email" in the Phrase Manager. Updates: Version 1.0.1 - Fixed a small error with checking the IP address.
