The facebook page 12YearOldSlutMemes encourages the sexulisation and vilification of young women, moreover it encourages facebook uses to "like" and make abusive, sexually violent comments about the young woman who's pictures have been reposted here.
No one should be abused and threatened for the way they dress, that this facebook page focuses this sexualised abuse on 12 year old girls is even more disturbing.
the page is clearly in breach of Facebook's own community standards regarding hate speech and the Statement of Rights and Responsibilities:
"Facebook does not permit hate speech. While we encourage you to challenge ideas, institutions, events, and practices, it is a serious violation to attack a person based on their race, ethnicity, national origin, religion, sex, gender, sexual orientation, disability or medical condition."
