There was no kicking lag in the game period. Pretty much everyone who's ever played against me in a slightly laggy game has seen me shank an extra point, and I aced all of them this game. Plus, he went for 2 on every single TD he got (4 in all), never even tried an extra point to find out if there was lag. PLUS, he hit a 32 yard FG dead center on his only attempt.
After two warnings, there's no excuse, I think it's bannable just because of that, but I'll defer to your judgment.
