Temporarily banning someone over posting about a win on a bet that they may or may not have made would be absolutely ludicrous. You don't get to call those shots, and you do not get to dictate to the mods what our course of action should be.
I get that this guy annoys you; hell, he annoys a lot of people. But truth be told, in this thread, you're getting your hackles up for a lot of nothing. If there were bets between members, where actual money was changing hands between members, with someone holding escrow, etc., etc., then yeah, there would be a problem. But this thread is just people talking about their NFL bets, asking about what would be the best type of bet, who they should bet on, etc. So, who cares if he actually bet on the Lions and made a ton of money or not? Who cares?? And if he really bothers you that bad, then I suggest you go to your UserCP and put him on your ignore list, and stop wasting our time with ridiculous stuff like this.
