ISPs have made millions. Part of their money-making strategy is charging child pornographers to upload child pornography.
So they can use the "I'm a common carrier" excuse as long as they want, but I think it's only fair that they are asked some tough questions about it. Why can't a team of lawyers review every packet flowing over the public Internet to make sure that nothing "bad" is going on? It sounds simple to me, someone who loves children but has no idea how the Internet or computers work.
Sounds pretty dumb, doesn't it? Why is Craigslist not held to the same (non-) standard as the ISPs? Why don't we just censor the entire Internet For The Children!?
