I've never been kicked, and I've only had vote kicks initiated against me on two occasions - that I found out about at least.

First time was when CT first came out, I zoned in in a bikini. I had switched back to my regular gear before the first pull, but the guy harassed me through the entire dungeon claiming I wasn't even fighting, and got his friends keep initiating vote kicks against me. Eventually someone put a vote kick against him and he got ejected - right before behemoth.

The second time, I was leading a T5 learning party and we had to DF 2 players. One of them started a vote kick against me while I was explaining the fight, which was quite surprising when one of the other players told me about it.
