If you enable PICS to screen rated material and block unrated material, you can allow the viewing of unrated material on a case by case basis with a password but again, because the greatest majority of Internet content is unrated, that gets old fast. What we strive to provide is an index where every site listed is rated according to its content. If enough people follow my program, for web developers the issue will become simple economics. Omit rating and lose market share. Make that market share big enough and they will lose revenue.
People listen when money talks.
Your support of this site by using it regularly will drive the changes needed to ensure that we get what we want, only what we want, nothing more and nothing less. What the Web should be. What the Web CAN be.
