Seriously Leviathan right now. Ul'dah to be completely specific there are about 4 of them spamming back and forth. You can't even type out anything this is absolutely unbareable . Put a chat filter like if you type out more than three times in a consecutive amount of time that you're banned from chat for a minute at least shout or something seriously. You can't even sell in Ul'dah thats how bad it is.
