There's already a limit of having a 4hr CD on initiating vote kicking to reduce the abuse. The system is not perfect - there are abuses but to me is the lesser evil compared to the pre-vote kick era - where people just join to AFK on you, and you see them nearly every single CM runs. Sometimes more than 1 player in the same run.

I don't know what else you can do, SE claims they do investigate abuse reports - how much manpower and money a MMO is willing to put into a case where it seems a small portion of the players are affected? I don't know about too many MMOs, but at least here the GM will come talk to you and ask you for more information. I played AION and TERA and all you get is a shitty automated response for harassment and cheating/hacking complaints.
