I think, I hope she is just highlighting the problem of automatic bots confusing the normies, and looking for solutions. She did not mention the DMV. I also think this is more about the normies, therefore not about Nostr. She, they pretend Nostr does not exist. I am quite sure they know about Nostr. They might not know, but because of nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m and nostr:npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9 they can't not know.
I think if you go to a more time consuming and more costly area, there are many algorithmic ways, and through interaction and what not to identify non personal accounts that pretend to be such. You can even employ FBI and CIA and military to locate the servers that create mass accounts and go arrest or bomb them. It is not just DMV and Captcha.
If they do that just with the centralized private services like X, Facebook, etc., they will achieve two good outcomes:
1. If they succeed at all to make a difference, amount of confusion for normies will be reduced
2. The more gifted normies will be fed up with excessive patronising, and will be pushed over the precipice into Nostr. Nothing wrong with that.
If I read her wrong, and she is actually after the plebs in Nostr, then that is a stupid waste of energy idea.
