Facebook and Twitter today are facing criticism from all sides after taking rare action to suppress an apparent attempt at blatant disinformation being spread three weeks before the election.

Both social media platforms are deprecating or outright blocking the sharing of a link to a story the New York Post published this morning about Democratic presidential candidate Joe Biden. Although Twitter and Facebook have both acted in the past to deplatform fringe actors, today's action marks one of the extremely rare times either has taken action against a story from a relatively mainstream outlet.
