Why is it important to know well shocking images ?
Banned images are always a historical / sociological attestation about how our society evolves through time by knowing this we might anticipate the future. I'm told that there are some absolute no go in the ad industry as Religion and Politics. However I think in some cases it is more important and even more benefit for an industry to break taboos and evolve our society by shocking people than to dick around with lame publicity no one cares.
