You never know with these things.I know some people have like 15 infractions and they're still around.Even Sam had lots of red cards before he was permabanned.Maybe he can tell us how many exactly.But, what the hell happened to you?I mean you really went over the top.Care to explain why?
Unfair moderation is what happened. When I was permabanned, I had 5-7 points on my infraction sheet and 12 infractions. 2 of which were for wrong scores in a match thread which were both accidents due to f**ked up livescores, and another infraction for posting a NT thread in GM (people do that s**t all the time and don't get infractions), so in theory I had 9 infractions. Now take a look here: http://www.menstennisforums.com/showpost.php?p=12598452&postcount=3251
BroTree has 33 (!) points. Does he ever get banned? f**k no. So I'm not sure how many points I had, but let's assume I had 7. BroTree has over 4 times the amount of points that I had, and I got permabanned for multiple rule violations while he still sticks around.
My point being: if the mods don't like you, they won't hesitate to kick you out unfairly. And judging by your bans, the mods don't like you. Take a break, it'll help in the long run.
