There has been a push to make this a nationwide requirement, but for now Louisiana becomes the latest state to require a Government issued ID to verify you are at least 18 years old in order to view online pornography
There's a "Check My Age" button . . . only government-issued I.D.'s work, like a driver's license . . . and if you're under 18, you can't get in. (Here's what the sign-in page looks like.)
U.S. Senator Mike Lee of Utah introduced a similar bill last month called the "SCREEN Act" that would do the same thing nationwide. ("SCREEN" stands for "Shielding Children's Retinas from Egregious Exposure on the Net".)
