Of course people will be dicks about it, that's how people are. If a person is being wrongly votekicked, they could just accept the fact that they're not going to play in that one server for a little while and wait for those guys to leave.
Alternatively, there could be a rule against it so you can report on general reports board with evidence proving your innocence instead of proving them guilty.
So if innocent players are kicked by a group of trolls they just have to accept that? How about no, this would cause more harm than good in any case. The general reports would be flooded and the community would die out because of trolls. You shouldn't have to prove your innocence when you've done nothing wrong in the first place. If there are people who are genuinely breaking the rules then report them on the forums.
If this system is added, there should be some restrictions, such as a certain amounts of people need to be in the room to activate it; you can only activate this once in a few minutes. Something like that.
Overall if someone's being a general dick, there's always the option to report them.
