Most of the kicks from L4D/2 servers I've heard of didn't have any obvious reason. However, I want to hear about the times you've been kicked for a semi/obvious reason.
Me first. I was just playing the last level in the dead center campaign on versus, playing as the survivors. The infected rushed and knocked everyone but me down. I ended up reviving every single one of them, surviving each zombie that tried to stop me. The other team got pissed and votekicked me.

post your stories of semi-reasonable kicks from servers in L4D or L4D2.
