All three default to yourself when no user is given, and all three have prefix twins:
,names,
,usernames, ,clearnames.
Privacy rules
/clearnamesonly ever deletes your own history. No permission · not even Manage Server · can clear somebody else’s names.- Only names that have been changed away from are stored, so the name you use now always shows as current.
- History starts at the first change the bot sees. Names used before that point can’t be recovered, and nothing before the bot joined exists.
Names come from member update events, which need the Server Members intent rather than
Presence. If the intent is on, history accumulates from day one without any configuration.
Moderation use
A member who spams under one name and returns under another still carries the same user ID, so/userinfo and /names together give the trail: current name, previous names, account age and join
date.
