gold sellers

it's been epidemic since day one. currently I have 53 gold sellers blacklisted. I've deleted 4 that have deleted their character. Someone in my guild said they had 125 blacklisted gold sellers. They send you tells, they spam in town constantly, and by spam, I mean spam... one after another. non stop. I just went to ul'dah after not being there for around a day or so real life, and upon arriving I was welcomed by not one, but two different gold sellers spamming.

There has to be something that square can do about this, it's really getting out of hand. Well, not getting, it has been out of hand since day one.
