They will be punished later for kicking you without one of the listed reasons: AFK, Offline, Harassment or Cheating.

1. This remains to be seen. Right now there's not even a way to report people found on other servers, so how are four people going to be proven to be abusing the function? SE also doesn't even seem to have enough resources to ban obvious RMT who have been repeatedly reported, so where are they going to find the time to investigate this?

2. Only one person has to initiate. The cooldown doesn't mean a lot as long as four people are willing to vote to kick them anyway - one of them probably has the kick available.
