AppGratis, which admitted that it had gamed Apple's chart rankings and whose CEO subsequently lied about its business model after getting its app pulled from the App Store, has now seen its push notifications to users shut down as part of a broader Apple crackdown on apps that attempt to manipulate iOS app chart rankings. The company, which charged developers a fee in exchange for promising to get and keep their apps into the charts, sent emails to its users informing them that Apple had blocked the push messages.
