I agree. Calling them is never a good idea. Even filing a lawsuit to get statutory damages is not exactly without its share of time, energy, and work. It is much easier and less costly to lie and fool legally ignorant victims to pay outrageous amounts of money.
The only way Higbee can file a suit for statutory damages is if the photo was registered with the copyright office within 3 months of publication. Otherwise they would have to prove actual damages which is a bigger pain in the ass for them. Making contact with them was you first mistake. Giving them nomoney would be your biggest.
