That’s bad.
What makes Sean town here?
Seanzie played very aggressively early in the day and attacked people using fairly weak, reachy cases. This is classic town behaviour. Many town players purposefully use bad arguments early in the day in attempt to generate meaningful discussion which is then used as a basis for stronger reads. This gameplay is typically bad as scum because it almost always results in a lot of players scumreading you, as it did for seanzie. Its much safer to play less aggressively on day 1 since you'll get a free pass for it as there isn't much to go on.
Seanzie's case on minish reeks of OMGUS. he seems to only think minish is scum because minish was scumreading him. Seanzie seemingly didn't say a thing about minish until minish made a post attacking him, at which point seanzie proclaimed that he had caught scum. OMGUS is a natural town reaction. When you know you're town and someone is attacking you, you naturally think "what do they gain from attacking me, a town player?" and so its easy to see them as a wolf if you can't get outside your own head enough, so this is another town tell.
Furthermore, Seanzie tried to start a wagon on a voteless player, minish, when he was in the lead in votes and deadline was hours away. I would expect a scum seanzie to think about how to live through the day and thus prefer a case on someone who already had votes on them like ex or DW. That he chose a completely new person suggests to me that his primary motivation in doing so was because he felt like they were scum and not that he wanted to survive. This naturally indicates a town perspective.
