So, what happened to the IRC room?

the room is still there, there has to be a way to ban all the bots

Depends what the efnet opers have to say about it really... if they want to do it they can, but honestly its the 3rd time this year, so I thought moving somewhere where there was control over this kind of shit might be a better option than sticking with the bugged out spam hole that is efnet.
 
Efnet opers have no power to do anything about it. That's the risk of being on EFnet.
