I DIDNT EVEN DO ANYHTING

You were muted for calling someone a dick, faggot, dyke, gay a couple times. Then after the mute you continued to do so. Edit: Calling someone a faggot/dyke/etc for not letting you create a fighter class isn't exactly "not doing anything." And a user stated her younger brother was watching her play and asked you to stop swearing, which you didn't.

you can't pretend you're cool by swearing -Notch :P
