I wasn't the one that banned you, so I asked the other mods about it and they said that you were in fact banned for being underage (and saying you were 12 in the chat) I also saw your aggressive comments towards other mods- being rude makes it less likely that you will be unbanned, and makes you seem more like someone that's actually underage.
Sorry for the late reply, just making sure I have all the facts correct before making a decision. ^^
(So you joined calichat one day to talk, only to find out that you were banned. When you asked about it in the comments, the other mods kept saying you were underage and said you were 12 in the chat, so you got a little angry at them. But that wasn't you, that was your brother.)
Did I get everything right?
Ah, I see! Well if you are actually 13+ and your brother did that, I'd still recommend apologizing to the other mods for the aggressive comments made (I believe it was Quade, Mordred, and Noki you commented to), and explaining that it was your brother. (It's the most likely way to get unbanned!) We do tend to jump to conclusions, but that's mainly to ensure everyone's safety. I'd explain it to them for you, but I'm going to be busy with irl stuff and school for a while.
