That is fair - however it does not have to be implemented by stopping the information from spreading. An alternative could be to refuse to distribute the false information without a disclaimer reading "DEBUNKED / FALSE / see here for fair balance" Or include a DIV to one side with a bulleted list of false claims. Consider the TRUMP quote image: https://pbs.twimg.com/media/CRxEt7pU8AAzekC.jpg https://pbs.twimg.com/media/CRxEt7pU8AAzekC.jpg People Magazine 1998 - I'd run as a republican because they are the dumbest. I'd lie my face off and they'd love me [paraphrase] A Facebook-fact-checker wouldn't have to suppress the sharing of the image. Id could create an overlay or add a subtitle or tag which reads "FALSE QUOTE - this isn't real" Rather than relying on the hundred million individual conversations being maybe fact checked - an algorithm / ai / editorial squad could apply fact checking automatically. The IMAGE thumbprint / URL flagged in the facebook database as proven false, it gets the extra-content on its own.
