I think most players care too much about keeping their roles hidden. I don't think it hurts towns to get multiple early claims from scummy players. I also don't think it hurts to get early claims from townies when those claims are helpful to sorting alignments (e.g. Varsoon's information, miller claims, etc.) or to avoiding catastrophe (e.g. Irrelephant's PGO claim). Yes, roles sometimes help confirm players as town (e.g. vig shooting mafia, doctor preventing a nightkill), but competent scum also fake these sorts of behaviors (e.g. forfeiting nightkill to fakeclaim doctor/bulletproof). I don't see why players place so much value in roles when they don't help nearly as much as people seem to think. From what I've seen, they often lead to mislynches (scum love to push mislynches through role analysis).
I also think most players put too much weight into investigation. I've seen scum fake investigative results in most of my theme games, mini or large. I've seen town get faulty results in half my theme games. I've seen town get mislynched because of faulty guilty results. I've seen scum get cleared from faulty innocents. The reality is that you never know if the investigation has been screwed with by a redirector, bus driver, lawyer, framer, etc. The benefit of investigations from my perspective is to corroborate behavioral reads (e.g. in RC's recent game, an investigative result corroborated strong townreads on NSG and scumreads on Nico), or to encourage players to reevaluate someone you've been townreading (i.e. to combat confirmation bias). I'd never lynch someone because of a guilty, nor clear someone because of an innocent investigation.
I also think the players talking about "game-throwing" in this game because we outed Varsoon's information are overreacting. We outed some information. So what? If he dies, he dies. If he doesn't, he doesn't. The benefit of outing him is that we're getting stronger townreads on his slot, as well as valuable behavioral reactions from Nancy. From my perspective, that's much more useful than keeping his information hidden. I feel more comfortable townreading both him & Nancy after this, which means we're refining our reads in productive ways due to Varsoon's play. It also hedges against the risk that he dies before he outs the information. I see this as a win-win.
