Definitely need to get a report post feature in there, I think we usually see the posts pretty quick and deal with them but still something we need to have.

I'm not sure if the captcha will help as I get the impression the spammers might be actual people rather than bots. But i'm not sure so it won't hurt to implement a captcha

Thanks for the suggestions. In the near future I'm going to go back through this thread and make sure I have everything on my list of todo.
