I understand, and even agree, that how this is being handled has some pretty creepy aspects. But one thing missing from the comments I see here and elsewhere is: How else should verification be handled? We have a real problem with AI/bots online these days, trust will be at a premium. How can we try to assure it? I can think of one way: Everyone must pay to be a member (there will still be fraud, but it will cost!). How else can we verify with a better set of tradeoffs?
There is some info from Persona CEO on (of course) LinkedIn, in response to a post from security researcher Brian Krebs: https://www.linkedin.com/posts/bkrebs_if-you-are-thinking-ab... . I note he's not verified, but he does pay for the service.
