BADecker's being doing this for years and has never been moderated. Might as well treat P&S as Off Topic 2 for all the spam in there. If you want an actual discussion on something, self moderation is a must.
Probably does need a moderator, although I do believe it'll be a difficult job finding someone who's impartial enough, that they don't just delete things that seem like utter crap because they don't agree with the users opinion, but also get rid of the stuff that is just low quality.
I don't think it should be that difficult. There are plenty of people in P&S who post absolute nonsense, but at least manage to mostly stay on topic and can make a coherent post, even if the content of that post is moronic. And then there are people like BADecker and Tash who just post low quality and off topic trash which contributes absolutely nothing to any thread.
We delete off topic posts and posts which add nothing in other boards. Why not P&S?
