Louisiana’s new law, HB 142, requires users in that state to prove they’re 18 or older before accessing sites that contain pornographic material. If a website’s content is a least one third porn, you have to show an ID.

This new law has many privacy advocates worried, and some researchers are warning about unplanned ripple effects of the law’s implementation. Marketplace’s Kimberly Adams spoke with Jordan Taylor, an internet and social media researcher and PhD student at the Human-Computer Interactive Institute at Carnegie Mellon University.
