I agree that shame can be a powerful tool, but I believe there's ways to have more impact than shaming individuals for being addicted etc. Crazy idea: why don't we shame the people creating addictive products for profit at the cost of their customer's health, instead of their victims? I saw a campaign in Paris last year shaming people who throw away packaging with pictures of stuff that didn't feel like it was necessary packaging in the first place, why not shame the companies that sell unnecessary packaging instead? Poeple who create and maintain these systems are who I think should feel ashamed at least.
