Why should the recipient/platform be culpable if the supplier is already acknowledged as being both culpable and dishonest as far as the ToS? It might be sexier in a David vs. Goliath sense to go after Facebook but Facebook isn't the party creating and uploading all of this content. If the risks of supplying a platform without consent aren't sufficiently high then suppliers will never have an incentive to verify consent. And if the suppliers were already verifying for consent then this would be a non-issue because consent would be implied as far as the platform was concerned.
