When in doubt, I tend to look at the less active players first rather than the louder ones, since inactivity can come from either being away or deliberately hiding.
On the other hand, I think it is fair to vouch someone for elimination if they are fishing for personal information or clearly trying to troll or provoke people, because that kind of disruptive behavior usually does not stop even after a scum gets turned into a fruit on a tree by the end of the night.
Someone in this thread has been asking a lot of personal questions about names though. It might be worth keeping an eye on.
