Who is AltDentifier?

Altdentifier is a bot that's employed to filter out accounts in #verification that it believes are alts or bot accounts, just to prevent spam or people trying to circumvent bans. I'm not sure exactly how it works, but it's most likely reading you as a false positive for a bot/alt. (It's been letting a few bots through, so I frankly wouldn't be surprised if this were the case.) If your Discord account is over 10 days old, it might be the string of numbers at the end of your username? Regardless, we should have a way to let you in manually.
