Facebook fact checks Ami Horowitz's post about lockdowns: Facebook claimed Ami Horowitz's post about Covid-19 lockdowns were "missing context." His post said, "According to Johns Hopkins, the lockdowns didn't help at all. Not shocking." Facebook added a notice to the user's post and linked to a USA Today fact check article. In a tweet about the incident, Horowitz said his account was also restricted but no evidence of this was available. Fact-checked posts lose exposure and are negatively affected by the platform's algorithm.
