Strange article. The web/internet also has no way to comply with this law. And nobody can speak for it, only explain how it works.
I find it weird to refer to #mastodon as a social network (but it's much more of a network than the closed platforms). Mastodon can refer to server software, an app, a non profit and/or a few servers that they run (wish they all had different names).
How can a law make enforceable demands on entities outside its government's jurisdiction?

Decentralized social network Mastodon says it cannot comply with age verification laws, like in Mississippi and elsewhere, and says it's up to individual server owners to decide.
