This was my solution to admin abuse in 3.x when I used to play.
I join a server, see abusing admin, I leave.
How does that solve anything? Admin/owner pays for a server to play with people. If he/she abuses and annoys players trying to play on their server, they’ll leave. Resulting in people avoiding the server, lack of players, waste of money.
Writing this comment I actually thought of an idea which I will go ahead and make a topic of it.
