Deleting a user blocks a user due to a deadlock condition with ghost user
Sentry error: https://sentry.gitlap.com/gitlab/gitlabcom/issues/24989/
We have users reporting that when they are deleting their account and try to recreate with the same username it is saying that your account is blocked.
To fix this currently, we have to manually unblock them from the admin panel.
