Is this a spam or shadow restriction when a GitHub profile shows 404 “User not found”?

Body

I’ve noticed some GitHub accounts that still exist (they can log in and use repositories) but their public profile pages show “404 – User not found.”
Does this usually mean the account was flagged for spam or put under some kind of shadow restriction by GitHub?
Just trying to understand what typically causes this situation.

It usually means the account was flagged by GitHub for spam or suspicious activity. When that happens, the profile is hidden (shows 404) but the user can still log in privately until the review is done or reinstated.

Probably the account has bee flagged as spam, and therefore cannot authorize a third party application
