Any mechanism that amplifies information also amplifies noise, something I think we didn't really understand when the web/internet started. Understand the provenance of information we see is still difficult, its not as if there is git log of changes in some concept or news item in some random website that goes back to whenever it was created globally. Even "blockchain" doesn't really fix the idea that it was garbage when it was inserted. Simple ideas like someone saying some words in a public context seems difficult to validate or verify sometimes much less complex ideas like climate change. Information is a messy concept made worse by the freeform nature of the internet/web.
