Stopforumspam.com for MyBB - Spam prevention
Dissalows registration to known spammers on the stopforumspam.com database
This plugin is aimed to help combat the ever present war on spam, this enables you to check all new registrations to your forum against the stopforumspam.com database to see if they are known spammers. It can check their username, email and IP address.This plugin is very configurable so you can dial in exactly the level of scrutiny you want, you can choose whether or not to check the users email, IP and username and also whether all their details have to match those of a spammer or just one of their details.
The plugin is very easy to install, it is just like installing any other plugin and requires no code modification.
At this stage the plugin is still in Semi beta as I have done a lot of testing myself but it is a bit difficult to test this kind of plugin from localhost.
Enjoy, Tim.
