There might be clever ways to distribute the job of censor, e.g. have an initial cadre of trusted users and ban any newcomer that gets voted down too much by your trusted users. Someone gets added to the trusted users if the existing trusted users vote them up sufficiently. Or something like that. But I expect you would need someone to experiment with the site full time for a while (years?) before the mechanics could be sufficiently well worked out.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
