How Do Online Forums Handle Spam and Inappropriate Content?

[Dal]

Dear Admin.
Please help us. There’s a threat under every subject called “horny girl wants you”. They've been there for two days so you might want to do something. Thanks.

um...what?

 

[Greg Bernhardt]

Yes Dal, please explain.

Umm...I can’t explain anymore. They’re gone now. Maybe I over worried about it. Anyway thanks Greg.
Btw, nice new PF layout.

We have whisked them away for safe keeping...I mean, deleted their massages...messages! and banned them from PF (physics forums, mind you).

Sorry for the scare.
