Well personally I'm actually not all that suspicious of FRAYDO at all. Irish, if he's telling the truth, would sound at least not-scum to me, but at the same time I don't know if I believe his roleclaim, and have just gotten kind of a scummy vibe from his posts. We've not had a role before like the one he's claimed, so it's kind of hard to find a baseline. I also do have some suspicion because of all the lynchproofs and my lack of suspicion on FRAYDO. I'll again throw in that Nodlied is at the top of my list, for partially the same reason, and the fact that he doesn't seem helpful at all. I just don't think we can do anything about him without shooting him, and apparently people don't want to do that (despite my hints about red velvet).
As for Chopbam, redirectors just don't seem towny to me, and the way he conducted himself at first was like he was tossing a grenade into the room to see what happens. There's also room for him to have extra actions via an item. I mean, if we don't lynch him, I'd recommend investigating him for items with your thief at the very least. But also like I said, Chop's usually sort of a blind spot with me.
And, for what it's worth, you're not completely clear in my book either. Item thief doesn't really sound too towny to me.
