I learnt about the above-mentioned project through one of Eastcoastlife's posts. The initiators of the project are Jon Harmon, founder of Force for Good, and Mihaela Lica of Pamil Visions.
Here's the message:
Please require a password-protected login before allowing even free access to explicit adult content. We understand that selling porn is your business and we respect your right to make a legal living. But understand our legitimate concerns and work with us. You already have the “warning adult content” on your websites. Yet kids, who are not legal customers of your product, ignore the warning. So to prevent them from having direct access to explicit images, texts and sounds, the simplest way is to have a password-protected login. No more “free tours” before a visitor supplies basic information.
