The Simpsons: Tapped Out Wiki:Semi-Protected Articles

Some articles are semi-protected on the The Simpsons: Tapped Out Wiki. A semi-protected article will only be available for editing to users who are autoconfirmed. To be an autoconfirmed user on the wiki, you must have been a user on the wiki for 4 days, and made at least 10 edits there. When an article is semi-protected, a silver padlock will appear at the top left of the page.

Even though some articles are only semi-protected, others are fully protected, which means that only users with administrator privelages can edit them.
