A couple days ago, I noticed the number of reviews for the iPhone Siddur dropped from 101 reviews to 79 reviews, over night. I scratched my head and forgot about it.
Apple must have removed tens of thousands of reviews. MacRumors said that SEGA’s Super Monkey Ball count dropped from 4197 reviews down to 3710. So logically, if you add up the apps and the possible number of fake reviews, those numbers are probably very high, probably in the tens of thousands or more.
