Administrators have the ability to protect pages so that they cannot be edited except by other administrators. In addition, protected images cannot be overwritten. If necessary, pages can be protected just against anonymous and newly registered users or moves.
Some pages may be protected due to continued vandalism or continued insertion of incorrect information. They may also be protected to preserve the integrity of the wiki. The level of protection will increase as damage done to the page increases. Most protected pages are to the Autoconfirmed level; however, in extreme cases, pages may be protected to Sysop level.
Pages with this icon have been protected because the page has been consistently vandalized or an edit war has taken place. This protection will only last for a short period of time. Only sysops may edit fully protected pages.
Permanently full protected
Pages with this icon are protected to sysop level by default because they are essential in running this wiki. They will never be unprotected, and in most cases, they cannot be unprotected. These include logos and stylesheets.
Pages with this icon have been protected because of vandalism or controversy. This protection is only intended to be temporary. Any user above the autoconfirmed level may edit these pages.
If you see this icon in the right-hand corner of a page you want to create, it means that only sysops may create this page. The protection was inserted to prevent spam pages from being created.
Pages with this icon have been protected to avoid the page being moved without authorization. It may be used in the event of sustained page-move vandalism, or as a prevention measure on high-use pages. Only sysops may move pages than have been protected in this way.
A permanent or semi-permanent full-protection is used for:
- Protecting high visibility pages such as the Main Page from vandalism. This includes templates transcluded to these pages.
- Maintaining the integrity of the site's logo, press releases, and key copyright and license pages (for legal reasons).
- Protecting certain "system administration" pages. This includes many editorial templates, such as deletion notices and stub templates.
- Protecting the MediaWiki namespace and pages transcluded to it. These pages affect the system interface for all users.
A temporary full-protection is used for:
- Enforcing a "cool down" period to stop an edit war.
- Preventing changes to a page while investigating a possible bug in the MediaWiki software.
- Allowing for history-only review during discussions on article restoration.
