There has been a glitch in the Temporary Banning messaging system. An update was being applied to a certain members account, and it applies that change to all of the banned accounts. So if you are getting a message that does not seem like it was your offense explaining your temporary ban, then it probably wasn't.
Please note: the temporary bans themselves are not glitched. If you were temporarily banned, it was for a reason. It is just the message that is incorrect.
