So if you want to get your competitor banned from the App store, just post lots of spammy positive reviews for their product? How would you defend your app against such an attack?
It would be a big risk, but one could potentially buy 'false flag' reviews - throw some negative reviews on your own product, and positive reviews on your biggest competitor - It would hurt yourself in the short-term, but could pay off if you can get the competitor banned. Again, super risky, probably stupid strategy... But with the state of the 'app' market, I wouldn't be surprised if people would try it.
Maybe I'm missing something, but it seems practically impossible to distinguish between the two unless there was a royal screw up somewhere along the line.
I think apple acted pretty responsibly here.
You just go on fiverr.com and pay someone in Indonesia $5 for the hit.
