That is already a thing if you are verified and one of the reasons why "blue checkmark for $2" (Elon's plan) won't work and will make many verified people unhappy. They don't want even more peasants and "cloud chasers" in their verified timeline.
Frankly, I think Reddit could do the same and give more weight to upvotes from those that prove they’re real.
It could help with disinformation problems and with finding signal.
<edit>I found the quote [0], which I had quoted in my essay "Why Twitter Should Verify More Users: Towards a More Human Web" [1]:
> Facebook’s killer feature was that it replicated the real world by forcing people to use their real names, whereas MySpace users used pseudonymous handles

I know one of the things I loved about Facebook was interacting with university-verified humans. Then it got flooded with more and more spam accounts.
I hope either these platforms or the next generation of platforms realize there is a strong opportunity for real-name policy platforms. It won't be the whole market, but I'm personally really tired of anonymous accounts. I mostly come to HN because there aren't many real-name platforms that talk about these things. Maybe that's because lots of people don't want it. I guess I just don't buy that argument. I think there's a niche for sure.
What makes you think users want any of this?
Frankly, most of the suggestions I've seen coming out of the SV "thought leaders" about what to do with Twitter are terrible. The bot problem isn't easily solved, and adding a ton of friction and/or reducing anonymity isn't going to be some huge boon to the platform.
