If it's an individual or group of individuals that only are annoying certain people - there's the mute button on the main screen. We even emphasize the use of this in our rotating notices on every server.
That being said - if you got a demo of them literally annoying -everyone- on said server, *then* we can do something about it - because it's affecting the server as a whole instead of individuals.
Hope that is clearer.
