Or are you saying that others should figure it out for themselves? Perhaps. In some situations, you would be correct. But at the end of the day, this is a game for town to, as a whole, find scum. In the situation I was referring to, Acrostic gave off the impression that he didn't want to give the information that he may or may not have had that could help differentiate town and scum. This is not something that one should do. If he was unsure of it, to the point of where he felt the opinion could change, he should have kept it in his head, or taken notes for himself. But making a post regarding one's alignment should, in most situations, be backed up with reasoning to avoid yourself, a member of town or one trying to pass off as one, from receiving unnecessary suspicion. Unless, again, you want this suspicion for some reason. I can't think of many where someone has made a statement and another player didn't ask said person for a reason. And in almost every situation, the person has either given their reasoning (allowing others to get more of a read on this player, based on how their reasoning was given), or they avoided giving their reasoning, and thought of as scummy.
And there I go rambling again.
