Certainly, there are always going to be people who gum up the works with junk posts. But my suspicion is that these people aren't likely to read or follow a list of rules to begin with. But if someone is frustrated with my app, I want them to go ahead and post that first "I'm frustrated with your app!!!" message, even if it contains no other information. With luck, I'll eventually be able to get enough information from the user to help improve my program...
