About Face appears to be fueled by feminists, but I strongly sympathize with their concerns:
[M]arketers are never going to show an ugly slob in an ad because no one wants to see a slob and we all aspire to something greater. But if all we see are unachievable representations of ourselves then certain unhealthy illusions of self are sure to emerge. And have. Just visit a highschool hallway.
About Face, whose mission is "to promote positive self-esteem in girls and women of all ages, sizes, races and backgrounds through a spirited approach to media education, outreach and activism," examines the portrayal of women, specifically, in advertising and comments on how damaging the images can be to the psyche of consumers. Part of the site has a list of the top ten marketers who, in the opinion of About Face, damage society through their imagery of women advertising.
