On this page you can find all of the users that are on the universal banlist.

These people will automatically get banned in Discord servers that have this feature enabled.
Only serious offenders will be added to this list, after a thorough confirmation of the offences.

If you'd like to figure out what their Discord handle is, copy the ID and surround it by "<@" and ">", so for example: <@457573832350236672>.
If you paste that into a Discord chat, you'll see what their username is.

To enable this feature, type -universalban on
You can find the file with banned players here
