The Monastery already has a mechanism in place to deal with this -- node reputation and experience points. If it bothers you then vote the node down and reply or /msg the OP letting that person know why downvoted the node. If enough Monks agree with you then the bad node reputation and lost experience points will likely encourage better behavior in the future.

Of course, as you may have noticed, massive downvoting of these nodes is not happening. And thus the community has in effect already said that this issue is not as serious as you make it out to be.

As an aside, you apparently have not really thought this out very well. What about code snippets? Code from other languages? Third party modules? Legacy code that cannot be changed? And so and so forth.
