Okay. I would call it 'ambiguous' more than misleading. It probably should say "...or has never logged in on to this Wikia account." It is also likely this error message is very old and wasn't updated for when all the Wikia wikis were unified.

As with any problem you see, if you want a chance that it gets fixed, you should report it to Special:Contact/bug.
