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.
