When the App Store launched, it was relatively bare, leaving it an untapped resource for new (and seasoned) developers. There have been many success stories, which have led to other developers wanting in; if you look around the store today, you might see hundreds of applications that do the near exact same job, except all by the same developer. This is a classic example of monetizing the community, without regard for quality, and Apple seems to have had enough of it. TechCrunch's MobileCrunch division is reporting that the developer Khalid Shaikh, responsible for 943 applications, has been banned from submitting any further products to the App Store.
Shaikh has been submitting to the App Store for just short of nine months, so as MobileCrunch calculates, with 250 days and 943 applications, that's about 5 applications a day, every day. And, sadly enough, they were pretty popular... no profit estimations were given, but it's suspected that Khalid was pulling in a few thousand dollars daily. Apparently, Apple claimed that they, "continue to receive the same or similar types of complaints regarding [his] Applications despite [Apple's] repeated notices to [Khalid Shaikh]." So, without a forewarning, they banned him from the Store and notified him via email, which we've included below for reference.
Shaikh said that he was going for lower product value and higher monetization, which means he prefers to build a large number of applications and set a fairly hefty price for them. This shows, as he doesn't provide much support for his business, and a large portion of applications have bugs. As you can understand, other developers were quite annoyed at his behavior as well, as much of his software is simply just aggregated news feeds or other very simple examples. If you look for the developer Brighthouse Labs on the App Store, you can find another operation similar to the one Khalid had going.
Situations like this point out some issues with Apple's reviewing process with the App Store, which a large amount of developers criticize, but hopefully they're learning from the experience. Again, here is Apple's email to Khalid, for you to peruse:
