Now that I've thought about it, trolls/spammers = want to post stuff and hence the way of banning them is to keep them from posting, whereas scammers = want to get people to send them funds and hence the way of banning them is to keep their credibility next to nil, where a scammer tag or the new rating system does.
Let me help out with your logic:
The way to ban scammers is ... by banning them. No more posts, no more PMs, no more problems, amirite?
I understand this is theymos' sandbox, and he sets the rules. I'm fine with that. I guess i'm also fine with this half-baked apologia. Nevermind.
Edit: This forum seems to be a big deal to Matthew. Please unban him, if for no reason other than "it's a nice thing to do."
Edit2 @Kouye: done.
