Counting wins by tournament awards is a bad example imo, because there were many many times where I ended up second or third, just because someone of the highest veterans kicked me out in the semifinals, and most of the time they were the same people. And just because I'm not better than them, I can still be a good player, or at least I know what I'm doing in the topics that I listed under my name.
For a filter, I was thinking about a minimum post counter, and a minimum time of being a forum member.
