NewsGuard claims to fight fake news, but it merely trashes web sites for which it has a political disagreement. It hides behind reviews that only appear to NewsGuard users and are not made publicly available in a manner in which they can be corrected or commented on. NewsGuard provides very little proof of its contentions other than claiming certain articles or false or saying there is disagreement about a certain point. NewsGuard is not a reliable source for information about fake news web sites.
