Webadict strikes me as exceptionally scummy. Every step of the way, he's been leading the assault on innocent townies, save for Eduren. Now, having both ICs as scum is unlikely, but alignment was chosen randomly, so it's not to say that it's impossible.
I'm almost certain that Vector would've deduced something like this (he was easily the second-most experienced in this game); he was nightkilled before Eduren was determined as scum.
Diakron is also a possibility, and Johbson, but if they are scum, I consider them less of a threat. Diakron's outburst seemed scummy, and it did seem planned (to me, at least); he was gloating about how clever he was several posts earlier. Sadly, I think voting him will end up getting another innocent townie lynched, so I'd like to avoid that if possible.
Lynching webadict now is really our only option — if we don't lynch him now and he's scum, we're as good as dead. If we do lynch him now and he isn't scum, we've lost a valuable townie but we can still recover. He'll likely wait for a bandwagon to form around someone else, (or form one himself) and direct his flock towards it, then take out two people tonight (one lynch, one NK).
Actually, looking back, Eduren's behaviour is suspicious. It's scummy, that's for sure, and it's a clever sort of scummy. Webadict was the one who attacked him initially (I think? He was certainly the one who lead the charge), and from there Eduren's arguments devolved more and more into archetypal scum arguments.
I think the both of them collaborated to make webadict look completely innocent; eliminating scum so early on via sound deduction is townie, and indeed, it's even within webadict's ability, but therein lies the problem: it's also the least suspicious thing you can possibly do, and that makes it suspicious.
Note also, that webadict's activity died down after he eliminated the major threats (Vector, Eduren). It didn't quite reach 'active lurking' levels, and it doesn't really mean anything (he probably didn't have any leads and didn't want to post incomplete reasoning), but it still seems strange.
I think we should hold off on suspecting the lurkers; if webadict flips town then we hit them. Eduren's lynch seemed too easy because it was; webadict knew he was scum from the beginning, and Eduren purposely acted scummy so webadict's reasoning didn't seem to be completely godlike.
To summarize, webadict is playing a very dangerous game of
Xanatos Roulette.
