Twitter has "community notes" now, which is something similar to what you describe. If something contains wrong or is misleading information the community can vote to add extra context to the bottom of the tweet that the author did not write. The note only shows up if people with a diverse set of backgrounds all vote that it is useful/correct. It's a feature that was introduced after the Twitter -> X conversion and it's a pretty good feature in my opinion. I have seen many instances of misinformation on the right being "community noted" where extra context is appended to the bottom of something inflammatory.
