Not a bad idea, although I'd start with a ban on medical - pharmaceutical advertising on Youtube. Most countries don't allow marketing of any kind of prescription drug (not sure about over-the-counter though), based on the very common-sense notion that only trained doctors (with no backdoor kickback deals with pharmaceutical outfits) should be advising patients on appropriate medicines for their condition.
I agree strongly, but my point is that in modern social forums the only difference between advertising and content is who is getting paid. I can promote my drug through traditional advertising, or I can promote my drug by sponsoring channels, or I can promote my drug by hiring a "viral marketing" firm to try and spread rumors about how my drug is so much more effective than the competition but being held back by an evil shadowy cabal of big pharma.
