I don't think it's the ad, per say, but the agreement for delivery. It's be like you sending housing ads and asking USPS to only deliver them to men. USPS would probably be on the hook then as well.
Back to your point though, it is a new domain because with your paper examples there is no one who can "undo" the illegal ad. You copy it at Kinko's and it's not like Kinko's is out there delivering it with you. With online platforms, they both Target and deliver these ads and are responsible for continually delivering them.
