I don't think anyone was suggesting that nobody should ever buy from someone that posts a dirty picture. Just folks expressing that THEY would choose to pass on something like that and giving their reasons why. A perfectly clean background on a photo is no guarantee of quality....just as a dirty cage is no certainty of illness or scamminess. But each is ONE PIECE of the puzzle you must try to put together yourself each and every time you choose to take the risk of buying an animal online from someone you don't know.
