If Xsyven wants to claim after smashman reveals what he found, we should lynch Xsyven. (I'm discounting the possibility that smashman's information flat out clears Xsyven, because I imagine smashman would have shared it already if that was the case.) Xsyven has at least hinted at being unable to claim and has otherwise refused to answer questions that it doesn't seem he should have any trouble answering. It's already been explained why he shouldn't claim after smashman reveals his information and Xsyven has flatly said he can't claim anyway. If he changes that stance now, he's contradicting himself and should be lynched.
I think smashman should reveal what he knows about Xsyven if he thinks we might not want to lynch him if we know it--he implied earlier that the information made Xsyven look town. That said, Xsyven hasn't been very helpful at all in the past few days, despite repeated attempts to get him to answer specific questions. I don't buy that he's restricted from answering any question we ask him--maybe he can't claim, but that's probably the extent of it. And if he would post at all it would at least suggest he wasn't just blowing us off and choosing to ignore our questions. So the threshold for "we might not want to lynch him if we know it" seems pretty high, but again, I don't know what smashman knows.
FWIW, if nothing else changes I fully intend on voting for Xsyven before the deadline. I adamantly oppose a no lynch today, but I'm not going to put him at L-1 just yet.
