When a create-protected page is undeleted, the title protection is not automatically removed. When one then re-deletes the page or moves it without redirect to another title, the title will still appear protected. This happened with the pages [[https://en.wikipedia.org/w/index.php?title=Talk:Stanislav_Shekshnia&action=history|Talk:Stanislav Shekshnia]] and [[https://en.wikipedia.org/w/index.php?title=Hedgewars&action=history|Hedgewars]] on Wikipedia, for example. Since undeleting a page changes it from a red link to a blue link, the expected result is to automatically have the title protection removed with a WikiPage::onArticleCreate call.
Now this happened with [[https://en.wikipedia.org/w/index.php?title=Stanislav_Shekshnia&action=history|Stanislav Shekshnia]] too.
Recently, this has happened with [[https://en.wikipedia.org/w/index.php?title=Clarice_Phelps&action=history|Clarice Phelps]] and [[https://en.wikipedia.org/w/index.php?title=Biju_sopanam&action=history|Biju sopanam]] too, and so this bug still hasn't yet been fixed.
Also, we should create a maintenance script that removes all existing pages from the protected_titles table.
