My understanding is that Special:MostLinkedCategories should display links to:
- existent categories with >0 members,
- non-existent categories with >0 members,
- (possibly) existent categories with 0 members.
On the other hand, it should *not* display links to:
- 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:
