Help, the sploggers are back!

I've really enjoyed being spam free for several months. Besides the few manual submits.

But it seems as if the spammers have figured my system out and they are attacking it with a vengeance!

I changed anti splog's 2 question security to recapcha and it seems as if it got worse.

Plus, there is one spammer that no matter how many times I spam there profile, they are still able to create blogs.

Is there anything else I can do to keep these idiots out?
