I've been getting a few reports a day on spam. To fix it, I went into the permissions and found out that (yikes!) "banned" members could post / reply / upload things on some forums. Also, after we set up the whole thing about new users needing to validate their account we didn't set the permissions so they could only read the forums. They could pretty much do everything members could do.

So, I changed some settings. We'll see what happens. Hopefully we'll be spam-free.

Thanks for all those who have reported it.
