The ISP's could stop 90% of it but why should they ?? it "might" cost them money

ISP's are not members of law enforcement. No matter what country you reside in, I assume you have some sort of "Rights" where you are allowed certain freedom to access the internet and that your ISP isn't part of the government or law enforcement. It is not within the domain of ISPs to "enforce the law." Moreover, they should not. If I were an ISP, the last thing I would want to do is to appear to take an active responsibility to uphold the law. That means that I would be placing myself in a position of responsibility, unasked, and I open myself to possible litigation, both private and governmental. If I actively, directly, searched to "investigate" infringements upon the law, I could be held responsible for "allowing" illegal use, just because I failed to investigate it.

Law enforcement is empowered to enforce the law, not private individuals or companies. A company can, however, act to protect itself an its interests and can report violations of that to authorities or, during the course of due diligence, it can report possible violations to authorities, just like any private citizen can. But, that's as far as it should go. We don't need commercial vigilante groups policing the internet, motivated by profit.

PS - Sorry for creating a second post, but I'm just not going to jump through having to edit my post in third-party sofware in order to include a response to yours, since copy/paste deletes the contents of a post and this forum doesn't allow multi-quoting. Sorry.
