Just ignore the players, turn off the public chat or stay anywhere that isn’t a pk zone. Block everyone that harrasses you.
You want breakfast? You gotta catch it!
We can't really do anything about the pking (pvp is a big part of the game) or the youtube videos (can't really do much with a third party), but as for the vulgarity, please report it in game so that a pr can deal with it. If nobody is dealing with it and you see me online, pm me and I'll see what I can do if I'm not too busy
