Seriously...some people spend too much time at the bank.
It doesn't take much to add people to the ignore list. Takes what...5 seconds at most? And if it's that bad page on him. Just because you page on him also doesn't mean you have to sit there and watch him either. But yeah, could sit here saying the same thing over and over, but some people apparently like to play this game to watch a spammer and start fuming off it.
Would be nice if there was a solid solution to fix this but whatever, in time hopefully. Even WOW has this problem though, spammers offering to sell gold and offering to train your own character for a price. Of course that's why when I played the game I was usually logged out of the global chat.
Apparently the obvious answers just don't click in some people...
