Would you not be curious what people were saying about you and your app? And would it not be advantageous as an app developer to know the feedback you are getting and be able to improve your app? I think these are the sort of reasons combined with the fact that people are very resourceful and persistent in obtaining your contact details make it very difficult to just ignore what people are saying. But its a good point and with some effort you could probably mask your identity to some degree, the trouble is once one comment has really got to you, it doesn't really matter.
