YouPorn is the highest trafficked adult website in the world and boasts a higher Alexa rating than both CNN and Weather.com, reports Portfolio.

But YouPorn and other blue Web 2.0 startups could be out of business in the near future if proposed changes to 18 U.S.C. 2257 are accepted into law.

Known in the industry as "2257," 18 U.S.C. 2257 defines requirements porn producers must follow to verify the age of every performer, keep records about the performers' identities and make those records available to the government. The proposed changes would extend the statute's reach beyond adult-content producers to include social networking websites.

That could mean every adult who wants to upload a naughty picture to a social network would have to submit a photo ID and state their full name, date of birth and other personal information.
The ostensible purpose of the law is to curtail child pornography, and no legitimate porn producer argues with that.
