This needs to be addressed, I have been given multiple suggestions such as:
1. You can't talk till level 10. (Don't like it myself, but there is always mumble and such)
2. Subscribe before you pay. (Not sure what it is right now, I myself and running on a free 30 day trial)
3. IP ban. (There is always a proxy, but in the long run it becomes to much of a hassle for the gold spammer.)
4. Sue the gold sites, they may get a little out of it, but in fact the Gold Spammers are harassing the players, which hurts SE's business. (Counter intuitive to a gold spammer, they might end up losing money.)
