The miller claim is inscrutable. They can't be reliably investigated so we have no mechanical way of testing the claim. We can only rely on behavior. Historically, the miller role has been criticized for having the opposite its intended effect; it's intended to make someone appear guilty when they're innocent, but in use it actually confirms players. This was a result of mods using the role more and more making Mafia less likely to claim it lest they be CC'd.
It's less common now, making it more viable as a fake claim, but old habits die hard. You have to commit to it early, which also discourages Mafia from claiming it. But meta changes and sometimes fake claims are given. I don't know enough about the meta here, or Pie in particular to really judge.
If we're down to LYLO and he's still alive, it'll be more of an issue. If he shows up on some watcher report, or someone risks an investigation on them (tracker, role cop, etc.) then the discussion changes. Right not there really isn't anything we can do about it unless you suggest a lynch him on principle.
As far as Supa. I don't like the claim at all. To be honest, I don't like these cagey habits he appears to have picked up. Unless he's prepared to provide something solid to work with, I don't think people should place stock in him. If he isn't prepared to provide something solid to work with, he shouldn't have claimed at all. It does seem like a deliberate fishing attempt, but he's a noob so that doesn't necessarily make him scum.
