You had trouble to get going this game. You didn't want to miss the boat and get called out as a lurker so early on you wanted good looking posts out to get off to a good start. There are two keys to this, first "good looking" and the second that it was forced by your gameplan, not naturally by other people's posting. So what we end up with are very early posts with lots of quotes and a stiff structure. So by page 5 we see a PBPA. That's straight up silly should you have been town. As scum however, it makes a lot of sense. The PBPA structure makes that getting a post out with seeming analysis is doable, it helps you post. And really, you'll always find something if you want to in those. PBPA's are fine. But not on page 5. On the same page we find a logical setup about a quote where the premise is very neatly detailed etc. The argumentation is similar. Sure you could do that as town, but more usually a town sees a post, quotes it, and points out what he's seeing. He doesn't need a setup at the time of what is the exit of the RVS.
Later on you get into your groove more, as expected. The start of the game is awkward for scum, you don't know where everybody stands and first impressions do count. But once that's past, you know what people want and who they suspect, responding to them and asking questions about it gets much easier, and as such scum posting would be expected to feel more natural. It's easy to blend in when people already have an expectancy from you.
Shame your early game gives you away
Surrender, imagine and of course wear something nice.
