You will have noticed that most of the spam that gets through the defenses, and gets subsequently reaped, is not by Anonymous Monk.

As for the rest of your proposed mechanics, I don't see a future for them. The site has worked well with these mechanics for some time now, and I don't see your arguments making a case why Perlmonks should change away from them except that other mechanics seem to work well elsewhere.

I don't see how eliminating "negativism" contributes - there are actual bad answers, and also out-of-place answers, and for both, downvotes seem to work well enough. If you take a "I don't like this" downvote as identical to "I don't like you", that's a personal problem, but nothing that this site or its mechanics can rectify.
