In an e-mail sent out to Play Store developers earlier, Google announced several updates to its developer program policy. The e-mail mentioned changes in policy including clarification to payment policy regarding subscription billing, the restriction of the "use of names or icons confusingly similar to existing system apps" (a statement that brings back memories of Facebook's "Messenger" gaffe), clarification regarding dangerous products, and practices that violate the Play Store's spam policy, all in addition to a stringent new Ad Policy.
Remember Airpush, the ad network that was widely considered one of the most intrusive, irritating methods of advertising in existence (so much so that Lookout released a special app to fight it off)? Well, it looks like the folks at SellARing (pronounced "sell a ring") have come up with something even more insidious.
SellARing's ad network essentially allows associated apps to replace the familiar "ring ring" sound you hear after dialing a number with a selection of 10-second audio ads.
