I know I risk being down voted remorselessly but I have to put this in context. Where in the real world is anonymity considered ok? If I only put a flyer through someone's letterbox here in the UK, I have to identify myself. If I sell a physical product I not only have to identify myself but take on serious legal liability. An author can take on a pseudonym but only via an identified publisher.
In fact that latter example might provide a solution. Set up a company willing to publish apps whilst hiding the actual developer's identity.
