In order to help stop some of the spam registrations here on the forums I have just added and enabled a StopForumSpam hook. This hook will check registrations against the StopForumSpam database, checking key factors such as email addresses and IP addresses. If their IP or email is matched in the StopForumSpam database, this user is automatically banned and cannot use the forums.
If you come across a spammer or even a potential spammer, please don't hesitate to hit the Report button so the Lunarsoft Team can look into it.
Edit: Since installing this it's blocked eight spammers within three hours.
