Meryem Ali got a call from her cousin.
"Meryem, what is up with you and Facebook?" her cousin asked in December 2013.
Ali said she hadn't logged onto the site in months.
"You need to get home and look at it," her cousin told her, "because someone's acting like it's you, and it's not you."
Ali soon found a Facebook profile of her filled with sexual, doctored photos of her, including a photo of her performing a sex act. She asked Facebook to delete the fake profile, then she asked some more. Finally, the social network did so in April.
