yah they should just work out some learning method to pick out stuff that looks odd & offer to clean it up. But i believe then it would require a thin layer of oversight and Google of course will not want to get involved. Apple clearly doesn't shy away from app store admin which is why they have the better platform at the moment.
Or they could of course just do away with the mechanism that auto-highlights 1-star reviews and instead you know.... ask the user what they want to see. As if people can't handle clicking a bar that says "Read 1 star reviews" a la Amazon.
I can't imagine why you would want to list 1 star reviews first... generally 1 and 5 star ones are the least informative (either "I'VE PLAYED FOR 5 MINUTES AND IT'S THE BEST GAME EVER" or "MY PHONE CRASHED WHILE DOWNLOADING THIS IT'S A VIRUS!!!", and 2-4 reflect though-out reviews.
