Thanks. Glad to see you're on it and have taken some action. Since I once co-owned a large forum (non-poker) I'm very familiar with people trying to beat the system with their forum posts. And yes, they get old very fast.
It's not up to me of course, but on my forum, I had no qualms about reducing people's point counts, even to zero. If they got mad and left, what had I lost? Nothing.
