If anything the sequence of events at that time make killgor and CS look scummier then it does Rafay.
Possibly, it doesn't point one way or the other much like many of the things I seen so far.
It is hard to say what is scummy, scummy can be anything and if it is anything how do I determine if it is scummy or not.
Was killgor scummy after he unvoted and then went on to vote as other make out? I don't know, all I know is that found his answers lacking.
Lacking answers could be seen as scummy.
KevinH could be seen as scummy, I don't know if I see anything particular scummy about him.
Your scummy is different than others peoples scummy, Nerau thinks/thought me and Rafay were scummy together much like you.
There many scummy views and none that are conclusive.
The only reason I see for Rafay not stating what role he is if he is scum or a normal townie.
