Here’s an announcement from Apple that you might easily overlook.
Beginning January 9, app screenshots will be locked in iTunes Connect once your app has been approved. New screenshots may be uploaded when you submit a binary for an update to an existing app or a new app.
Paul Ducklin, for Sophos, explains what Apple has actually done here: i.e. taken action against an all-too-common scam.
Produce a legitimate, uncontroversial but not terribly interesting app – something you can do quickly and inexpensively – and get Apple to approve it for sale in the App Store at a modest cost.
Then do a bait-and-switch not of the app itself, but of your promotional material, dropping in a screenshot from a well-known or highly professional app to make your software look like great value for money.
