Most information is fact-checkable
So there are a few categories to deal with:
Completely made-up stories designed to fit an agenda / provoke a response / propaganda e.g. the pizza restaurant. Easily disputed but not immediately.
Facts which have extensive scientific evidence. These can be checked quickly.
Opinions and ideology which can't really be fact checked.
Challenges are that there are a significant number of people who reject science or claim it is biased or invalid; and that opinions are often presented with 'facts' which may or may not be correct. IMO ban the whole thing if it contains any false facts even if it also has true facts.
Given the amount of checks and balances in place within science that remove bias, require experiments, substantial evidence, and peer review by people who also have lots of evidence and expertise in removing bias, looking for mistakes and issues with other people's findings, IMO there is no higher standard that can be applied to fact checking than this. Who else is going to put in that much work or that much rigor?
