Is taking photos of other people's photos a genre of photography?

The image on Flickr is already down so someone must have complained. I've never heard of this as a genre unless it's in the context of a collage, sampling other photographers images. I think this is clearly a case of copyright infringement and fraud. Photo labs that copy photos are quite careful to make sure that there is permission given by the photographer when a client comes in with an image to copy. Otherwise, they are committing a crime. Theft is always offensive.
