Alright, I had to "voice" K_C and LadyShoes in order to temporarily get around it. I did a ban because the trolls who join will usually REjoin after you kick them anyway. But if you're using mibbit and you try to get in before Jewdo fixes it, you're SOL.
So yeah, Jewdo. You've got a bit of a mess to clean up. My bad.

And please, for the peeps who keep saying this is too hard to figure out, allow me to give you a list of some of the flaky broads who have managed to enter the chat on many occasions:
Myself (the flakiest, since I'm a bit trigger happy with the chat banhammer)

"It's too hard" is no excuse.
