I am curious as to what effect you think this has on encouraging anyone to not post anonymonkly?

Seems like the carrot is once removed from the stick in your attempt

Mind you, I am of the personal opinion that posting is a priveledge that should be reserved for registered users...so much so that this restriction is in-place on my Everthing implementation - (as an aside I am not advocating this as a change here, it is simply my opinion) - but I don't see how your approach will influence anyone as only anonymonk is impacted by your downvotes.
