Well, to reverse the question, what about one-liner posts is town to you? Don't you dislike the lack of content to read? After examining your PX case I don't see anything wrong with it, so I'm still willing to work with you. Even if it's weird when you're talking. 
I don't think it is town but I also don't see it as scum. He posts one liners everywhere else too, and I just doubt that a role PM magically changes his posting habits regardless of its alignment. And yes his content is thin but you can say the same about PX and Headcrabs, so I see still no reason to put above PX.
Again do you have any reason to think that PX is town aside from your ?maaagical something? and meta?
While the reasons for voting PX have more or less been said in different guises already, it worries me that none of the people on the wagon have actually delved into why PX over headcrabs, and to a slightly less extent, rawr, the first two of which are scummy for similar reasons. Would be nice if everyone could order those three potential lynches into some system of ranking. Dorian. G for me stands out as taking the path of least resistance so far, going for Dan and PX for elaborated but more or less standard reasons and taking the not so controversial town reads. He does not have the advantage of a history of side suspicions that Bardiche, BT, and others had, and so I'm quite wary of him. Might be something for tomorrow.
Well I'm really sorry that I wasn't able to bring up new and innovative revelations but I stood under the impression that I would have only limited time to push the only scum read I had then against an established wagon on one of my town reads, so I may have rushed some things.
Now to your question, I think I already made my point on Rawr clear (see above) and about Headcrabs, even leaving his role aside have I trouble to see him in a scum team, nor any kind of team. The only setup with scum Headcrabs that makes sense to me would be a set up pawn sacrifice that get bused at the next best opportunity. Considering that he got through day one without being voted even once is this a unlikely scenario.
So far so bad, I made the mistake to look into the more recent post and I have to say that what Rawr said there doesn't even begins to make sense.
Next post PX ? goddam
