There's a few problems with scenarios that you encountered. One, the fact that there are quite a few idiots out there who's sole purpose is to get off by ruining everyone else's race. Two, when the game is in "RACE" mode, it locks out anyone trying to join even if they were wronged.
There are few people out there who know what online racing is about but not enough to password the game at this point to block the yahoos. Even though I have admin powers to boot the trouble makers, once the race starts, the only thing I can do is restart the race and boot the offenders I did that last night but you must have already left the game and could not get back in. We'll keep trying until we get a good race going.
