Guardian is awarded by admin(s) of Khan Academy. There's no official policy for normal users to become a moderator. Therefore, you can say that it is truly hard to earn the badge.

From my personal experience on Khan Academy, I saw some users, who already earned Guardian, have less than 10 answers in their discussion history. I doubt some admin(s) could have given wrong badge to these profiles (Guardian, instead of Fact Checker).

Short speech: It's up to the admin/staff mood, similar to Friendly Hacker case.
