backend(ish) suggestion:

[for admins] user objects could be saved with an extra array called “vanity“ or “slugs” or something where admins could add extra url vanities for users, that redirect to that user, e.g. the official wasteof account could have the vanities /users/wasteof and /users/admin that redirect to @wasteof.money. this would mean people could fine the admin account without finding other accounts that look like staff because of their username. This could also be nice if you want to get /users/jeffalobob to go to /users/jeffalo without making a whole other account that has the link in its bio or something. I was thinking this only as an admin tool, but It could potentially be a feature with a limit so people don’t have to create accounts with similar usernames to not be confused.

Vanities could only be usernames that aren’t in use or are banned for something like impersonation of another account.
