Old news. Facebook told us in a developer blog entry months ago that the auto-ban bot looks at user feedback such as hides, comments, uninstalls, mark as spam, extended permissions prompt acceptance rates etc. And you as an app developer can actually see all of this data through the Insights feature of the developer app. Too many developers have their head in the sand and think just because they have 1 million users and a 4 star review rating that everything is peachy. The fact is there are a ton of crap apps that spew out BS. Maybe the user who installed the app thinks it is great to spam all of their friends' feeds, but when those friends hide the app's posts, mark it as spam, etc. then the app is going to risk auto-banning. I know folks on HN don't play Farmville or spend all day on these apps like fortune cookie, quiz of the day, etc., but bazillions of FB users have nothing but app-generated posts on their walls.
