It's the same problem as with email, which is largely solved, for those who care, by filters in servers and client software. This could be done completely independently of any protocol or user behavior in usenet. It would, however, require an investment by _somebody_, likely the ISPs, but since usenet is so lightly used compared to email I wouldn't hold my breath.
Again, if you want people to take you seriously or get behind you, have a proposal that makes sense that provides a genuine means to get you (and a lot of others) something of benefit. Just showing up, spamming a bunch of disinterested newsgroups with an OT message, and complaining without any apparent clue of how to solve the stated problem is just going to, well, just has, annoy people.
That's a death-knell for usenet. The beauty of usenet is that most groups are unmoderated and belong to no-one. If you want a moderated forum there are web-apps for that or discussion groups that already exist. Why take away the big benefit of usenet to make it just like everything else that has popped up?
Who picks your "self-moderators"? How much authority do they have? How do you police the moderators? It sounds like a way to create another Wikipedia-like disaster.
You've gotten the discussion going. You should listen to the responses rather than discounting them.
