Leading up to our Presidential election January 2020 we have adopted two strategies. One is called “notice and public notice,” which means instead of taking anything down, when we noticed that there were, for example, a trending rumor that’s going viral about painting the protesters from Hong Kong as “rioters that have been paid 20 million to murder the police,” all these of course are not taken down but we work with independent fact checkers, like Tawan Fact Checking Center and so on, members of the International Fact-Checking Network, to trace the origin of that alternate caption.
