Vote kick whole alliance wide, please.
This matter was brushed in another thread and I have personal experience of the problem as well. In normal party, vote kick needs majority vote. This is sensible, even if in 4 man parties, two friends is enough to abuse it but that's another matter. However in 24 man alliance 4 people are enough to hold everyone else hostage by their antics. While they are far from majority, there is no way for the other alliances repel such grievers letting them make the run miserable for everyone else.
Report for abuse works quite well.
I have actually seen people get week long suspensions for abusing the kick mechanic. On my alt the FC was in there was another member who got a suspension for harassing a CT raid gloating about how people just click the yes button on kicking people without really considering. He got the good people kicked just to get a kick out of trolling then a few days later he was slapped with a suspension for harassment. You can bot, cheat and pretty much do anything in this game until you either RMT or harass people. SE is pretty good about harassment.
