Oddly enough there appears to be little control on the internet for this kind of infringement of civil liberties. This is strange as nasty spam is now on the increase. I get all sorts of nasties in my emails which could turn the stomaches of those of a more delicate nature.
The FBI have a dept devoted to internet crimes, so maybe there's the place to start.
The more that people complain the sooner this growing menace will be curtailed.
