"An unknown anonymous user" is not actually a user, but that's the text used to represent Wikia contributors who have not logged in to an account, otherwise known by their IP addresses. Anonymous users can be found on wikis all over Wikia.

They should certainly not be able to edit user rights... Looking at c:diary-of-a-wimpy-kid:Special:Log/rights, there are three entries for user rights changes by "An unknown anonymous user" around 2011. However, the log summaries "Kh2cool promoted Turbo Furbo to be a chat moderator on this wiki." appear for each one, indicating that Master ventus (renamed from Kh2cool) actually performed the rights changes, and Wikia simply hiccupped and failed to record his name as doing so.
