MOST SHOCKING

• "A friend of mine has posted pictures of the car that he had sex with a highschooler on top of. (he's in grad school)."

• "A friend's abusive boyfriend added me as a friend under a pseudonym."

• "My sister's fiancé sent me a private message, telling me he saw my picture, that I look good, and if he'd seen my picture before meeting my sister, then WE'D be the ones getting married. I've been barfing ever since. So inappropriate."

• "going from being in the closet with my family to out and selling necklaces i make to homophobic relatives in one weekend… just because someone caught me checking my profile on my BlackBerry."

• "An old high school acquaintance requested to add me as a friend, which I agreed to, then a few weeks later they proceeded to send me a serious message asking me out on a date and "hook-up" because they had "always had a thing for me" even though my profile indicated that I was married and I had a ton of wedding pictures posted."

• "i got poked (well more than once) by seemingly straight fraternity boys who's messages went from "hey whats up do you know so-and-so" to "hey come suck me off"

• "I'm adopted and I found my birth mom on Facebook, and apparently, my 11 year old half brother."

• "My friend tagged me in an old photography project (in which I was dressed as a dominatrix) on her profile. I didnt think anything of it and my boyfriends mom saw it and was secretly mortified that her son was dating someone who was so into S and M."

• "When one of my close friends had been in a relationship for over 3 years and her boyfriend broke up with her by logging into her account and changing her relationship status to "single"….and just waited for her to see it."
