Ask HN: Is there a good list of usernames to block such as 'about' and 'legal'

I'm planning on launching an site with vanity urls (url.com/username), and I don't want someone grabbing something like url.com/legal for their user profile.

I've googled and found 1 or 2 lists for usernames block impersonation in posts (like 'admin' and 'moderator'), but the vanity URL introduces even more concerns.
