Oh, yeah, that! Those are safety measures to ensure total loss of information. That way, the black hole won't regurgitate quantum instructions on how to reconstruct whatever was tossed in. Also, you can't revert something being tossed in a black hole, because the physics that occurs inside the black hole is too complicated for the BoF to untie.
