personal experience: I won on the last lap of the race against the leader of the room, I overtook him cleanly without collisions or contact, through a legal area. And the room admin, when I was reconnecting, banned me, and this last time he banned me for 12 hours. We cannot continue like this.

While it is sad to see I agree, this has nothing to do with LFS in general and you should contact the admins of the server you played on to discuss it.

I'll use your username as a suggestion to you - chill bro! It's their servers (we call them servers and not rooms) and in theory they can do it with it what they want to,even ban you for winning if they're such bad losers. Best advice - remember the server and it's admins and don't join them anymore,there are few other options in demo servers list,some say MRc and AA servers usually are well admined. Also consider upgrading licence and join organized events - admins of those wont risk their reputation by banning people for being faster in fair way.
