How would you automate a system that throttles low quality posts? It relies on downvotes. When people downvote your comments, you are "rate limited" for a short duration.

That, of course, leaves open the problem of people downvoting stuff they disagree with, regardless of quality.

Essentially, the system works, but in many cases, a downvote means you're right and the downvoter doesn't like being wrong. That causes an unjustified throttling. Oh well...
