The ISP's aren't allowed to monitor what's going on so it will never happen and no-one will ever work out how easy it is for anyone to exploit such a insanely stupid idea from the very start?

Their job is to make sure you're vulnerable to exploits and attacks.

How else can they justify their secret police and steal insider trading info?

Oh yes, if you have time to kill look up how many overpaid clowns on boards of directors have spook connections.
