It's been tried before. Maintaining the list is very difficult for the exact same reasons that would have made PIPA/SOPA technically inept.

e.g. http://en.wikipedia.org/wiki/PeerGuardian

Also it's definitely a shotgun approach, and tons of innocent people would be affected. For example, bluetack's most conservative list level1 (http://www.iblocklist.com/list.php?list=bt_level1) includes any organization with significant intellectual property.

Such lists continue in wide use. Of course they are not foolproof, but it does help.

peerguardian and it's ilk don't help at all. they make uninformed people feel safer.

Is that true? Could you let me know where you got that info from so I can check for myself? Thanks!
