Ask HN: How would you launch a verified-user first, Twitter-like social media?

Inspired by the question an hour ago about how you would launch a privacy first social media. How would you go about launching a social media platform where the emphasis is on verifying users identities to confirm they're not bots.

In my view it seems like social media nowadays is being overrun by bots spamming crypto, onlyfans, or just straight up misinformation. I feel like there will be a growing number of people who are disenchanted by the growing number of these bots on sites like Twitter, Facebook, Youtube, Instagram, etc. that could be convinced in using a site where there is verification of users as real people as part of sign-up. Additionally, I would assume advertisers aren't fans of potentially paying more money than they need to when the views on their sponsors or ads wouldn't be real people.

My specific questions would be:

1. Is there even a sizeable enough market that people would go through a more complex sign-up process to gain access to the platform

2. What would be the safest and fastest way of doing personal verification that can't be easily bypassed by bots and wouldn't leak PII from users?

3. How would you go about marketing a platform that would be targeting this specific niche?

Also, if there are any platforms out there that specifically target getting rid of bots please let me know.
