I’m suspicious of the green checkmarks and red crosses in this context. If the argument is convincing you don’t need it. If it’s bogus the nice design may take your attention away from it. A convincing design is more important to propaganda while a convincing reasoning is more important to fact checking. Of course a site may serve as both, propaganda for the ones unable to reason and carefully crafted argument for the interested.
