We can expect that, say, [[User:Jimbo Wales]] won't actually have any edits on the majority of our wikis. Does that mean there's no need to check for spoofs of that username?
Add an exception list. You can't expect a simple heuristic to get it right in every case. [[User:Michael]] once created LiveJournal accounts impersonating myself and a number of other English Wikipedia sysops. Do you think any anti-spoof technology on LJ's site would have prevented this?
We have lots of users with no edits. Among them, famous people are surely in the minority.
