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.
