My understanding is that Special:MostLinkedCategories should display links to: 1. existent categories with >0 members, 2. non-existent categories with >0 members, 3. (possibly) existent categories with 0 members. On the other hand, it should *not* display links to: 4. non-existent categories with 0 members. Case 4. originates from 3. by removing a page from the respective category or by deleting an unused category. Links from case 4. are currently displayed in the Special:MostLinkedCategories list - this is the point of this bug report. Also note that Special:MostLinkedPages and Special:MostLinkedTemplates do not contain links to non-existent pages/templates with 0 links/transclusions. Some links to show you what I mean: https://en.wikipedia.org/w/index.php?title=Special:MostLinkedCategories&limit=500&offset=1500000 https://wiki.archlinux.org/index.php?title=Special:MostLinkedCategories&limit=500&offset=1500
I'm just adding that this behaviour may allow a malicious user to leave traces of e.g. spamming or defamatory Category names by just adding one article to such a Category, whose "wanted" name would appearently stay in the list without the possibility of being removed.
