Looking through the last game the first three votes were all random. Two of the voters were innocent and one of them was the seer.
With that said, early, random votes do have a really good role in promoting discussion like the one that's currently going on. Nothing to make people sit up, pay attention, and actually engage in some serious talk amidst the banter than a good ole lynch vote! Voting for people just because they voted randomly is going to do nothing but give the baddies something else to hide behind.
That said, we don't have much else to go on...
