I suspect that getting criminals to pay you might be difficult - and blackmailing them sounds dangerous ;)

Botnets do it. It can't be too hard.

Isn't that the other way around? Botnets sometimes blackmail (random-ish) ordinary folk into paying off criminals, rather than you getting criminals to pay you?
