One of the other things that comes up a fair bit, is that some folks don't understand the difference between a short-duration mute and a ban. The majority of the bans I personally have issued (virtually all, to get insta-banned you tend to have to do something REALLY against TOS, posting porn, scams etc) started with one or more mutes from a couple hours to a few days. Very often we will use a mute to end a problem, we KNOW folks get salty from time to time, it's part of life, and an enforced cool-down usually resolves the issue with no further trouble, and they come back after the mute expires to generally be just fine in the chat.
But we often seem to have folks not understanding that a 1-day mute is *not* a ban, and will instantly start raging at us in DMs. Obviously, that does not tend to end well for their continued existence in the chat. Incidentally, you're *highly* unlikely to come up with anything we haven't heard of before, and unless you call us nazis and threaten us with "talking to the devs" we know you don't even care. xD
