Not going to happen.
In the first place in most cases, even the victims don't react properly by even complaining, the whole mess has turned into a gambling game where you bet on 5-10 numbers in the roulette, and if one hist the jackpot you're happy if not, you try again. The number of scams has grown so much poeple are just accepting it, I've seen tens of posts of poeple getting scammed directly with fake mining gear shops and most of them just brush aside the loss and say they've learned something, 1 in 100 actually goes and makes a complaint to the police. The fake girl trader who picks victims on tinder? Never heard of somebody actually willing to go further with legal actions after being scammed.
And with their ICOs and DEFI is even hard to make a case against, they could simply hold the sale and then do just minor work on the "project" letting it fail, you won't be able to get a life sentence for negligence, and if you change the laws that way you probably would end up putting 90% of the management teams of all companies in prison.
The scammer knows this, while you might get rid of some low-level ones with the bigger ones it's hard to do so, and those are the ones that take millions out of the pockets of foolish investors. Was EOS a scam? Would/Could you send someone to prison for it?
