The Facebook Wars

Mack Daniels was just another normal guy getting on his facebook account. Then he got hacked. The hacker, "Unknown" takes an intrest to his friends, or at least an intrest in manipulating them. "Unknown" sends multiple messages to Mack's friends, making them think that he has him held hostage. Will Mack be able to get his Facebook account back or will he have to cooperate with "Unkown"?
