Twitter is exploring ways to crack down on misinformation by crowdsourcing efforts to flag misleading tweets, the Washington Post reported.
A Twitter spokesman, however, denied that such a feature was being tested.
Two anonymous sources told the Post the initiative could take the form of a drop-down option that appears on every tweet, allowing users to flag posts with harmful, misleading or false information.
On Thursday, Facebook announced that users will no longer be able to edit previews of links that they post, a feature that many believed allowed fake news sites to make their links appear more credible.
