The Oversight Board-- better known to many as the Facebook Oversight Board-- has invited public input as it formulates a "policy advisory opinion" regarding the Meta corporation's so-called "cross-check" system. The R Street Institute respectfully submits these comments in response to the request for public comment issued by the Oversight Board in connection with its consideration of a request by Meta for a policy advisory regarding the “cross-check” system used to help detect some “false positive” content takedowns in certain circumstances.
