In most cases, accounts are globally locked if you break either the Wikimedia's rules or two or more of the site's rules. Your account has been not removed completely from Wikimedia, data from your account is still here, and it might be still possible to regain access to your account.
Why Wikimedia globally locks accountsEdit
Wikimedia wants to ensure everyone has a chance to be safe and keep it running, Wikimedia and it's sites has the right to:
- Block a account or IP address from a site for a short time, or indefinitely.
- Block a IP address globally or globally lock an account with or without notice.
