Pleeeease?
No really though, 3/4ths of the time global is being spammed/trolled etc. and the only thing that we can do about it is wait it out. What if someone decides to get a macro to spam the chat 24/7, or there's a big cat fight on it. No mods, can't ban them from the chat. Make an antispam that at least makes it so we can still talk if someone tries to spam it. This is pretty much the suggestion, I don't think I need to say more.
