Forum:Someone added a hidden category to my wiki.

Someone (or something) called QATestsBot added the following page (and category) to my wiki: http://theland.wikia.com/wiki/Category:Pages_with_broken_file_links

It doesn't seem to have any content, and I don't know what a "hidden category" is. Should I be concerned about this? My inclination is to delete the page, but I wanted to make sure it's not something the Wikia staff is doing for some reason. Teknomage (talk) 13:29, September 22, 2012 (UTC)
 * It's an automated addition a category that will list pages that link to nonexistent images. Hidden categories are categories that are only visible when the user specifically enables it in their preferences. To hide a category, add __HIDDENCAT__ into it.
