As soon as the industry gets wind about this practice people or servers or companies will get sued (there is after all nothing else these companies can do) and as soon as this happens some people in the line will try to protect them.
Could be server hosting company, the server hosters, source code Providers etc etc.
Btw that doesn't change the law: dependimg on your country there are already clear legal rules regarding lending digital copies to your friends.
They might fake users and start collecting data through those etc.
But only if it becomes a thing.
I think the main reason I'm not seeing anythinguch about lawsuits today is due to streaming services and the amount of legal media traffic compared to things like torrent.
