But that is US law, as of literally just this week!

> "In fact, under the laws that the Supreme Court just upheld, prosecutors in Tennessee and South Dakota can even reach across state lines and prosecute writers on FELONY charges for a single paragraph of sexually-explicit writing on my site that they think "harmed" kids in their states, facing up to FIFTEEN years in prison, for failing to implement ID-checks on my dinky little free WordPress site."

I think that's the point of the article. The Supreme Court has Ruled:

   "prosecutors in Tennessee and South Dakota can even reach across state lines
   and prosecute writers on FELONY charges for a single paragraph of sexually-
   explicit writing on my site that they think "harmed" kids in their states,
   facing up to FIFTEEN years in prison, for failing to implement ID-checks on 
   my dinky little free WordPress site."
