I appreciate your concerns here, although I disagree with some of your assumptions. For example, the very idea of an anonymous communication to the public is to build a place in the community for your idea completely separate from yourself. If someone wanted badly enough to take credit for their idea, they would become a member and post their idea from an account with at least some minor trace of authorization, authentication, and accountability. Without the "three As", there's no place at all for the person in any group, but the idea is still out there. That's the very point.
