Yes, there is already "censorship" every time a post is reaped. The only question is whether another particular kind of posting should be censored as well. And not even censored in an absolute sense, if possible, but somehow discouraged more strongly than the current system allows, since that isn't working.
Another thing to consider: maybe as long as only one member is doing it, BrowserUK and other experts can keep up with replies to all his harmful posts, pointing out to newbies what's wrong with them (though I don't know why they should be obligated to do so). But what if there were a dozen members doing it, or he retired from his day job and could post 12 times as often? Would they still be able to alleviate all the damage with replies? Should they have to?
PerlMonks is the most open forum I've ever participated in, other than unmoderated Usenet groups. That's a good thing in a lot of ways. It makes the site very welcoming for newcomers; even those who post without reading the most basic instructions are treated respectfully and generously helped. But that openness and desire for loose enforcement of standards does have a downside, in that it can be taken advantage of by those who shamelessly flout the voluntary standards of the community.
