|Contact Facebook and let them know what's going on. Chances are, they'll kill that account and let whomever is doing it (likely someone your daughter knows and has pissed off......ex boyfriend, ex friend etc) to not do so again or they'll have their account(s) closed.|
Unless the person responsible is liabling your daughter, there's not likely to be any "legal" recourse.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
