The JH Movie Collection's Official Wiki:Protection policy

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 Autconfirmed level; however, in extreme cases, pages may be protected to Sysop level.

Full Protected
Pages with a gold lock 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 a red lock 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.

Semi-Protected
Pages with a silver lock 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.

Create Protected
If you see a sky blue lock 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.

Move Protected
Pages with a green lock have been protected to avoid the page being moved without authorization. This may be due to page-move vandalism, or as a prevention measure on high-use pages. Only sysops may move the page.
