Does this happen on a particular server or on every server you go on?
If it happens on every server you log onto, then it might be caused by something you are doing.
Did you fail to read the rules for each server on the Welcome Page as you logged on?
Do you spam the chat box with nonsensical characters or random words?
Are you constantly asking people to give stuff to you without showing a willingness to at least do some things yourself.
Did you go straight to playing Multi-Player without first playing Single-Player for a few days?
If the answer to any one or more of these is “yes”, then this could be the root cause.
This isn’t to excuse any bullying if it’s truly going on - that’s uncalled for. But players who obey the rules and have worked to learn the game don’t have much tolerance for those who don’t. It’s pretty universal.
