I'm a unix system administrator and have administrated many forms. I can guarantee you that there are automated plugins to deal with this type of abuse so that the admins aren't constantly manually fighting this battle.
Can I block posts, emails and messages from specific users?
If there are particular members that bother you and you do not want to see their posts or receive Private Messages and Emails from them, then you can add these members to your 'Ignore List'. There are several ways to do this:
Through your User Control Panel: User CP, Settings & Options, Edit Ignore List. Then, type their name into the empty text box and click 'Okay'.
What if I see something offensive?
You will find 'Report' links in many places throughout the board. These links allow you to alert the board staff to anything which you find to be offensive, objectionable or illegal.
They are persistent buggers...
Still nothing like a year ago - the "record" is about 240 posts over a 4 hout period.
Quite a few read the baba voodoo black magic love potion posts - not naming names, but some of you really should find a girlfriend - just sayin...
