Playboy is trying to drum up some publicity for their magazine (which is not profitable- it's basically a loss-leader for Playboy's other ventures). Posting a fake picture of the Virgin Mary, in a Catholic country, is going to get a lot of responses. They're trying to get people's goat, and you fell for it.
Come on y’all, if the word Playboy wasn’t behind it, it could be considered a nice, art photograph. It is less nudity than one would see in many images of the Virgin Mary that are considered classical deceptions.
