Look, let's face the goalie and get to the puck.
The adult side of the web is a strong force to be reckoned with. The commerce dept. is the be all decision maker of the web anyhow in the U.S.
Even if the Supreme Court and even the friggin' Justice League

came up with a way to censor this or that, another country would spring up with their own form of the web and everyone would run to them to get their smut. There are countries chomping at the bit to be the new web hub.
All ya need is phone lines and puters which there ain't no shortage of.
The web is making way too much money for everybody and it's biggest attraction is SMUT. Plain and simple.
So what can be done? Whatever can be done had better be done fast as new technologies are ready to launch within the next two years.
It all boils down to taking responsibility on all fronts to make the web safe and lucrative. Since not everyone is going to play along we may well see quite the fight ahead. Problem? The U.S., Britain and the allied countries can crack down on only their citizens but that would just push that very profitable section of the web into the hands of foreign groups who have no ethics. Would make em' stinkin' rich overnight.
Will be interesting to see what happens in the next year or so.
