Actually, the release I used was dated. The signature on the release was dated. The reviewer apparently wanted the date of the shoot, not the date of the signature. This is something new from Shutterstock
My new releases have that along with all the other nonsense that IS has decided to require but this model release was older. I've used this model release for years with no problems. Since the photos and the release are several months old I hope they don't suddenty change the rules.
