I'd say a good start to your approach might be to contact these designers to see why they put these shots on Dribbble. Maybe the first Yoda shot was an exploration from a moodboard the designer created to show a client - the point is you have no idea why people put up a certain shot on Dribbble. Start with asking a question rather than that "...Useless Design..." blanket statement that you posted.
