@Ash: It's extremely hard for me to think that a town player would really try that hard to find scum by saying people are trying to blend in? First off, if either of the later two to say plenty are townies, they would have no idea the alignment of those before them. Therefore it seemed like an underhanded and stupid jab at Wall-E, instead of finding something more significant/relevant.
@Steph: There are always reasons for questions. I don't care if the question is how old are you, or why did you step on that cat's tail, but there's always a reason.
I would've rather taken option 3, actually looking for some valid points to go after somebody. As to your take on Wall-E, the way I see it is that you wanted to vote for him, so asking him a question is trying to (like you said) help or hurt his case as a scum/town player. Even that is an underlying reason to ask somebody about their playstyle. Heck, I probably would've ignored your question like Wall-E did until you brought it up that it was so important to you, and still probably wouldn't have given you a non-sarcastic answer.
Who really knows who's 100% innocent other than a sane cop (or insane with counterproof) and the mafia? As town we have to take some chances from time to time and voting who we think is most likely scum, not just people who are 100% scum.
@ryan: I'm glad that you've finally got your 3rd and 4th post in this game, but I don't think I agree with your opportunism rationale. Especially if it was only a FoS, it's not a vote so it's not really hopping on a wagon because of one other person. In fact, he was the first one to vote for LZ, and remains the only one so it's not a well populated wagon at all.
@LZoner: Basically nailed it right on (and in a nicer tone!) Except for your last part, being cautious is all fine and dandy, but explicitly saying that you're most likely going to vote for somebody, then going back and saying you were just asking questions to see their response does seem to me like that person is worried about being under the spotlight, so to speak.
