The only thing that can be accomplished by releasing the names and addresses of someone's spouse and children is to put them in harms way. That harm might just be getting yelled at but it could be much worse. Which puts this act into the category of "threatening someone's family"
As someone who agrees with Anonymous on the facts I would only support a small fine for violating someone's privacy. But for involving their family I would support and encourage local governments to send the members of this subsect to jail
