I haven't gotten any spam tells recently that I can remember. But I tried to track down one of the spammers once. They were in the instanced starting zone. If SE hasn't done so yet, I think they should put a heavy /tell restriction while in those starting zones. Like the moment you send a tell to more then 2 or 3 people it should lockout tells for X amount of time, with X amount of time being greater then 10 minutes. When I say 2 or 3 people, I don't mean 2 or 3 tells, it would allow you to talk with a person or two, but if you try to spam while in that zone. I typically found that I would keep getting tells from the same person until I black listed them.
