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?
