How Many Times Does A Question Or Answer Get Reported Before It Is Removed? Surely More Than Once?

I’ve had quite a few questions and answers both removed here lately. Most I have managed to get restored when I appeal them, but it makes med wonder–how many times does something have to be reported before it’s removed? It happens so much I am starting to suspect that one report does it, but surely not. Even something as shoddy as Craigslist requires five flaggings before removal.
