Please sign it to raise the awareness that we want to protect minors from this evil addiction. 

WE PETITION THE OBAMA ADMINISTRATION TO:

Regulate Internet Pornography

Regulating the distribution of internet pornography is crucial. We petition the government to keep pornography away from minors by demanding and enforcing that a valid credit card number belonging to the adult viewer is provided at a login screen to every pornographic website.

We also request that advertising is made illegal on internet sites containing pornographic images or video.

These two simple steps are absolutely necessary to regulate the distribution of pornography and end the exponential increase of pornography among those 17 years of age and under.
