Alex, if you see this, I can state for sure that it's a continual problem in the Tombs every evening. Just spend a little time there and you'll find practically one in every district it seems. There's no escaping them.
I'm about ready to turn local off and switch to the trade channel in tombs. You can hardly form a group without spammers cluttering up the chat and scrolling your LFG off the view.
