jerk moderators

have you guys ever been on a server and theres this mod that just does not like you at the start? or he is just crazy with power? well i have and i am sure some of you have to. for instance i was on this skyblock server i will not mention names out of respect for the server.and i was muted for some unknown reason! i didnt say anything bad or sexual but i was talking to my partners when i got a message saying no one can hear you. and thats that.i tried to tell people that i was being muted but i couldnt cuz you know i was muted.and some times around you run into mods that go crazy with power and ban everyone but those are a few things i ran into.i just want to ask the admins of servers to choose your moderators wisely and then you run into mods that you know are the best you can get.they help you and they ban people that do bad things like a mod should do.i would appreciate comments telling me about your experiences with moderators.
