TBH, I'm not used to being so widely townread, especially by the likes of Robz.
However... I am the Tracker. At first, I thought I was doing a pretty terrible job of tracking, because all I've had are null results. I think I'm pretty much guaranteed to have hit scum at least half the time, though, it's just that either they haven't targeted that night, or blocking shenanigans have happened, though the latter is less likely than I might have thought at first.
N1: Eevee -- he was on what I considered to be the scummiest position on the Joseph exile. I tried to breadcrumb that I thought he was more innocent going into D2 because I'd had a null result (see the middle of post #459).
N2: faust -- after Glooble flipped town, I was worried about the "one scum in {ADK, faust}" likelihood, especially because faust has been heavily pushing Glooble and refusing to scrutinise ADK when the wagon evidence alone didn't warrant it, and even though I'd pushed him for reasons behind being so set on Glooble in-thread.
N3: Galz -- he was terribly awol, and I know my frustration with his lack of interaction with the game was showing in-thread. However, an absent scum can still be puppeted by present scumbuddies in the scum QT, so it seemed worth a shot, and it seemed like the only possible way to get alignment-indicative content from him.
N4: faust -- as I said, going into the night, I really thought faust-Didds seemed like the most likely pairing, and with Didds topping most people's scum lists, I figured that faust would be more likely to take the targeted action, given that if they're the scum pair then they know there's a tracker out there.
As I said, all of these were identically null results.
The existence of my role does mean that scum has a two-shot role-stopper, which is how they presumably killed EFHW N3: role-stopping her to prevent the doctor shot from taking, and then using a regular NK to get the job done. That means there is one rolestopper shot unaccounted for, i.e. my target could have been rolestopped on at most one night. I haven't actually confirmed with Swowl whether his interpretation of the "twice at night" means both shots could have been used on different targets on N3, or whether it needs to be different night. For scum to end up no-killing last night, I suspect it means that both rolestopper shots have now been used.
Note that from N3 when scum pulled out the stops to take EFHW down, there's no point in them using their godfatherer shot, so that makes the expected number of scum targets per night lower. When I tracked faust in N2, the godfatherer could still have been expected to be using shots, whereas when I tracked Galz N3, if he is the godfatherer (which I think is likely, with Chairs being the Siamese Cat) then there was no point in him targeting, since the godfatherer shot only protected them from EFHW's role and she was guaranteed to be out of the game.
