I've recently implemented Forum Fortress for the site:



It's a pretty new product and they're working out the bugs - we're an 'early test site' so if anyone notices any spam that gets thru please report it.
With that said - it's doing a marvelous job so far of keeping the site clean and I don't have to juggle a million plugins that still let stuff thru like before.
 
Thought I'd post an update...

The blocking is now very, very good and stopping a phenomomal amount of junk and it's yet to catch anyone legit in the net.
If anyone has any problems due to this extension do let me know but I think we will be keeping Forum Fortress around!
