Opening an account on one of the platforms that require "Real people" confirmations, such as Facebook, was opened by one of us even before the first block of bitcoin was generated.
At that time there was no idea about decentralized platforms (that is, maybe there was, but the question is who knew anything about it), then personal data was not protected by laws as it is today, then we more or less shared a large number of our data when logging into those platforms on Web2.
With the arrival of Web3 and the inclusion of money in the story (through crypto), many became more cautious and less active on Web2 platforms and switched to Web3 where there was no need to present themselves with personal data.
In this way, they kept their identity, because is it wise to post your full name and place of residence, when you have tens or hundreds of thousands of dollars in your account.
Many also avoid crypto exchanges that require KYC, so it is unlikely that they would easily identify themselves as "Real people" through profiles on Web2 platforms.

The pictures you post, blurred, always show a pretty woman with blonde hair, so even though I didn't see your face in any of them, I could confirm that you are a "Real" woman.
I don't know how hivewatcher chooses the accounts from which they will ask for this kind of confirmation, but I hope they won't ask me what they asked you, because I certainly wouldn't give them a link to my FB account. Probably through the rare pictures I posted on Hive where my face is visible, they easily discovered my FB profile, but I wouldn't confirm it with a link.
I think that any Meetup (or mutual personal acquaintance) is quite enough to confirm Real people, as meesterboom confirmed in your case.
