In Texas, Florida, and more than a dozen other states, users who try to access the world’s largest pornography website are greeted by a surprising sight: a message on a black screen telling them they’re blocked because of the actions of their state legislature.

The Supreme Court seems likely to uphold a law that would ban TikTok in the United States beginning Jan. 19 unless the popular social media program is sold by its China-based parent company.

Congress labeled the app’s Chinese ownership a national security risk and passed a law that would ban the social media platform unless it was sold. TikTok and creators say that violates their free speech rights.
