Do you think there is any chance my friend's going to get in trouble?

ok so my friend made a "smut" list about slutty girls @ my school. She put their full names on a paper and printed alot of copiess.She posted them all over the girls bathroom and in some parts of the school and most of the people in school found them and were like "oh you were on the smut list" The girls that were on it were very very angry. Alot of people don't actually know who made the list. But do you think my friend can get arrested for it or anything?
