Some Wikipedia pages are protected from editing to prevent vandalism and the protection status is usually shown as a padlock at the top left of the protected page. It is of varying colours depending on the level of protection. These levels of page protection include:
- Full protection
- Creation protection
- Move protection
- Upload protection
- Pending-changes protection
Only administrators and office staff are able to activate page protection.
The Main Page of Wikipedia has permanent protection because of its high visibility, and many of the pages linked from it may also be protected. Note that page protection is done for protection against vandalism and not for censorship reasons.
