Actually its not all that surprising - people often assume that all photos of wildlife or insects are just a camera and a photographer going out to find stuff - and that does and always will happen. But many shots often take a lot of setup, sometimes using food lures to draw animals to a specific spot, using staged setups (many photos of subjects like mice and other smaller mammals are often done in small temporary enclosures because of the fact that normally they are simply not possible to get close to for a human).
My view is so long as the subject is not put in harms way and is not left stressed or injured then it shouldn't cause any problems.
