The general rule is that contributions must, first and foremost, contribute obvious VALUE to an Open Source project. That is a very broad definition, so we added the rules and guidelines to help stir contributors in the right direction and make it easier for moderators to recognize when value exists and when it does not.

We are working hard to ensure our moderation team approves only the contributions worthy or rewards, and has all the tools and instructions to execute the Utopian vision of rewarding quality contributions to Open Source projects.
