It is specifically because you got banned for "being under 13" it comes from someone asking a question like "How many candles in this photo?" then you reply "7" then they edit the message to say "How old are you" and voila, underage ban.
What you are overlooking is that Discord is the new MSN Messenger, YIM, etc your friends are not backed up in a meaningful way, nor the servers you're in, if you lose your account, you lose contact with basically your entire internet life and friends.
Discord should not keep those IDs longer than a month at a time once the user is unbanned it should be deleted a week later, or removed from that panel altogether.
