A protected page is a page where certain users are prevented from editing and/or moving the page. This can range from preventing new and unregistered users, to allowing only sysops. Only a user with required permissions can edit or move a protected page. Likewise only sysop users can protect a page in the first place, or unprotect the page to lift the restriction.
There are several reasons why a particular page might be protected:
- Pages may be protected because they have been repeatedly targeted with vandalism or moved to bad titles, or where it is believed that vandalism or page moves would have a unusually severe impact.
- Pages may be protected due to counter-productive edit warring, edit warring occurs when editors who disagree about the content of a page repeatedly override each other's contributions, rather than trying to resolve the disagreement by discussion.
- Pages may be protected when they contain statements or policies that can't be changed without following a certain approval process.
