EDIT: in response to Genny, but for all, really.
Yes, but how do we become certain? Do we wait until Cycle 2, or do we debate more? Each way has some merits (I've already expressed a desire to avoid lynches this one cycle). My avoidance of lynches this cycle will bow to near-certainty. It will not bow to much else.
Q: Are we certain?
A: Probably not.
If we mislynch, worst case is the mafias and wolves (I'm assuming there will be some) and/or other neuturals will ally by Cycle 2 (3 seems reasonable, but this is worst-case) and soon destroy us. I doubt there will be many deaths Cycle 1, so it is to our advantage to wait one cycle, I think. Worst-case is not likely, which is why I'm willing to take that risk. As far as I can tell, any lynch now is, as Engineer Pikachu mentioned, we likely will be shooting in the dark. Why not wait long enought to light a candle first?
EDIT: Ok, ok. I guess a reasonable suspicion will do. Lynch and delete Porygon3.
EDIT: Changed back to no lynch. I'm willing to give him another chance (but only one more, I think)
EDIT: For the record, I'm reluctant to lynch this cycle, but I guess we have enough evidence to give it a go.
