Ideally it would be a crew vote situation. A kick vote is proposed and then voted on.
This has been an ongoing problem with the only solution being to implement a kick feature. But Muse won't do it. There is a lot of potential for abuse and negative use.
The trouble is, their CA system is useless. They have no power and must take any and all abuse from players. But if they give them real power, it'll mean Muse will have to actively monitor CAs for abuse which will be another job. Which comes back to the kick solution. It's the only real viable solution to the problem and all Muse has to do is deal with complaints, which would be much better than dealing with reading reports.
