That's awful on Seprix. I'll cut him some slack because it's a tiny game but still
I don't think there is a "still". L-1 is 4 votes, that happens super fast.
Isn't it 5? we are nine
It's 5 to lynch, so 4 is "lynch minus one", and it's customary to announce when you're voting someone up to L-1 because the next vote on them (the hammer) lynches them with no way out.
Oh, and if someone right after Seprix voted Iguana there would be no way back? Folly.
Yeah, one more Iguana vote at that point and he'd have been dead. We'd still have been able to talk for a while, then the mod would have declared his alignment (though not role), and the thread would lock for night-time.
This voting is really different from in-person games I've played. There, we would make a "guillotine call" on a person if we found them suitably suspicious -- guillotines being a less racially charged concept than lynches! If that call was seconded (only one second was required, no matter how many people were in the game), the player was given a chance at an uninterrupted defence speech, after which we moved to a hidden vote, so there was no information available about who actually voted to kill whom.
Here it's very different, and one of the primary ways of getting information is to look at who's on what "waggon" as the voting happens.
If Iguana flips scum, then chances are his scumbuddy is someone who wasn't on his early waggon, because they'd want to try to avoid losing their team-mate so early. However, if he's actually town, I look quite scummy for pushing on him for so long, but the last couple of people deserve a lot of suspicion too, because a scum player might want to hold back till there's a probable mis-lynch and then push a hammer quickly.
With this many newbies, experienced scum might be hoping for some high-variance voting and a bit of sheeping, which makes Seprix's silent L-1 look fishy.
Anyway, add a load of WIFOM to all that (especially regarding motivations of experienced scums), then reason it through for yourself just to be sure.
