The constant gold spammers. This issue is unresolved as I've had my blacklist full now for a few months. None of the spammers have been deleted.

This is annoying even with my sound for /tell turned off, it still spams my screen. Oh, why don't I just turn off /tell? Because when friends log in and see me on, that is typically how we communicate at first. Or oh yeah, that's how many of my requests for assistance in dungeons, etc. comes in. So this is a very annoying issue that needs to be dealt with. I even went as so far to request more space for the blacklist or to make it unlimited. Or to have an in-game auto report system for users added to a specific list.
