Yeah on Cactaur it is bad.

I went to general options and shut off my /tell function so I can't see tells and then because they couldn't send me tells they begin inviting me like nuts and spamming me with invites.
So I put up /busy

I shouldn't have to put up with the hassle of doing this every single time I log in the game, SE I understand you make money off these guys purchasing new games or a subscription but this is getting stupid as hell.
I am becoming very annoyed I have to take my time from enjoying the game to Blacklist non stop, /busy non stop and had to shut off /tell option because its no longer used for players only trafficking RMT sales.
