Facebook does this and even requires some users to upload a photo ID to prove their identity[1], and that site is a cesspool.
A side effect is that people like me, who have no desire to create a public index of everything they've ever said or done on the internet, will not use those products in any capacity.
Hah, I deleted my account months ago and made a new account with a made-up name that literally has the word "Fake" in it, just to keep tabs on one or two groups whose events I'm interested in. Didn't even know that there was a risk they'd try to verify it.
Counteranecdote: I made a fake account for work purposes (needed to look at certain things on Facebook that you can only see while logged in, and didn’t want to use my personal account) and it got deleted pretty quickly.
My wife tried to create a new FB account a month ago after many years of not having one. Entirely genuine, real name, photo and cell phone number. Rejected as deemed to be fake.
YouTube implemented real names and that was an absolute shitshow. Not only did it fail to meaningfully reduce toxic content, by removing the protection of anonymity it enabled cyberbullying based on demographics: "Oh, now I know who you are I can more effectively harass you based on your sexuality/gender/ethnicity/etc."
They rolled it back for many reasons, but that was a big one.
Yeah, now if you state an opinion that's too controversial or against the grain you get blacklisted by anyone with enough time to feed your name into a database.
Have you seen the lowest common denominator facebook feed? Plenty of people will post plenty of garbage of their own volition even if you ignore just sharing other sources of clickbait and that's under their own name and face most of the time.
Reputation tracking is most useful for detecting bad faith actors (ie the person "just asking questions" but regular participates in extremist forums), but doesn't seem to be enough to promote any sort of self moderation.
Even for disinformation that wouldn't work very well. Reputations are made to be gamed even without it being a concrete thing, proxies exist, and it in itself is something exploitable for misinformation.
There is no easy epistemological shortcut to the truth (barring say mathematics and other verifiables), let alone the grey area of deliberately misleading truths.
Edit: Proposed this as a solution for disinformation agents. Guess I picked the wrong sub-thread to place that. Sorry for the confusion.
