In the early 2010s I worked for what was then one of the most popular browser extensions called web of trust. Users could mark websites as trustworthy or not and they’d appear on search results. It was far more than that behind the scenes with some fairly advanced algorithms to avoid abuse and rank users trust ratings higher than others.

I kind of feel that we are going to have to go back to something like this when it comes to LLMs trusting sources. Mistruths on popular topics will be buried by the masses but niche topics with few citations are highly vulnerable to poisoning.
