sorry if this is incredibly stupid but I don't want to add a character if it doesn't warrant..

I want to make an article on DC villains and I came across information on a being called Head.. it says he leads a "protection racket" on a planetary scale.. I might be showing incredible dumbness her but what is a "protection racket"? is it a criminal thing? I just wondered.
