Instagram Copyright Report

I received a message from another photographer on Instagram who had found one of my images on this person’s Instagram along with dozens of her own and other photographers images. He is tagging himself and the model, excluding me (the photographer) and placing his own watermark/logo on the image to make it appear like he is the photographer. It seems he is using other photographers work to attract models, although I can only speculate as to exactly what his motives are and why he is stupid enough to actually tag the model, as it would seem likely they would notify the photographer.
