The genies have escaped the bottles; the crap is everywhere
Just like trying to rein in "AI" it's impossible to stop the flow of data/information once it is in the wild.
Huge penalties might work if you can catch the perps. But many of these types live in countries that don't exactly care what other nations think.
We need to look towards a future where all known data points are public. Every person, every location, every bank account, every personal interaction, etc. If it isn't this, then it'll be massive state firewalls blocking data transfers.
What will our world look like then?
