Then enforcement will target companies providing residential proxy services.
In whatever country they are.
I am not saying this is the magic bullet that will make it all go away. Some will, some will not.
Enforcement’s aim is not to completely eradicate crime: make it anti-economical for the majority and it’s a good deal enough.
Go to Berlin and torrent a movie: you will be fined, for a few hundred euros. Can you VPN and get away with it? I suppose so, but your average Joe is just not going to do it: why pay 10 euro per month on a VPN and risk? Just rent it.
DDOS is also, in general, a criminal charge. What would happen to prices once you get a few inducements? If it’s a crime and enforced, what are the roles of App Stores that let users download residential proxy? Are they also committing a crime? Residential proxy can be used for legitimate purposes? I don’t think that line of defence worked well for Pirate Bay, no?
And yes pirate bay is still around, some scraping will always be there.
