I can understand why if you are actually playing with someone who acts like what is described as PGS's attitude it could be off putting. I've played one guy in particular who would allow mistakes through until it actively affected him or would yell for a judge to try and get out of something. I don't like playing him but when I do it drives me to beat him to put him in his place. Obviously not everyone is like that so yeah PGS could be rankling. On the other hand though, I don't have faith in what people say until I've seen it first hand. Apparently people form his store are sharing stories of how he was dickish but they're doing it from an effectively anonymous source with the backup of absolutely unconnected people doling out upvotes cause PGS insulted them or their play style.
Forumwise he was vocal. I never saw him actively target users, just broad statements. I don't see why he was banned, if it was for voicing his subjective opinion, albeit loudly, I find that a disturbing.
And finally, this is my last post on PGS, unless he returns. While I have an opinion about him, it is only based on one aspect of his life (his forum posts) and, like McFoy said, I had better limit my opinions from that experience because I don't have first hand knowledge of him outside the Internet.
And since I agree with how CBMarkham summed things up, I'm going to quote his post down below. Give it a read if you haven't already.
Edited by SabineKeyEveryone calm down. The general consensus was that he wasn't the devil incarnate or an obvious Hitler clone, but that like all of us, he was an individual with a few flaws.
PGS valued the rules and he valued winning and he had strong opinions. Those things are all fine, but the way things have gone down for him are probably an indicator that he also should have tried to see the value in having positive social interactions that were enjoyable for all parties. X-Wing is a community.
He had many points and many arguments that were valid, but the methods he used to make those points and the "tactics" he used to make sure that the rules benefited him whenever possible, ultimately proved very self destructive and I assume that they made everyone unhappy, probably including himself when it was all over.
My hope is that eventually, our boy PGS learns to express his opinions and still pursue the things he values (winning and the rules of the game) in ways that are good for both himself and the community. Let's leave it at that.
