I think they should look into the matter when a person is blacklisted by an undisclosed amount, but not necessarily auto-banned. I would like to mention account wide blacklisting would be pretty darned helpful as well. If we had account wide blacklisting, an RMT would have to buy a new account each and every time they wanted to /tell me. As is, they are off making a new character to spam the world with by the time I've got their first character on my B-list.
