I assume that many already do this. There's certainly a number of business opportunities in this, and it's only a matter of time before it turns into an arms race: people building fake social-media identities, other parties (governments, big internet players) deploy AI to distinguish these from real,... rinse and repeat ad infinitum. If I still cared enough about writing software I'd probably do a startup around some of this. Instead I'm writing SF about it.
