Kill-Joy has already locked his vote, so this is for anyone else's reference:
In my experience, locking a vote is usually a good guy strategy. It shows conviction and, to be honest, a lack of strategy.
Bad guys need to be more flexible and adjust their voting to suit such. They need to be able to change their voting at the last second (to look like they're part of the mob usually)
Eruantien's role claim was a bit overly-excited and silly from a new player, but two things outshine this for me:
1) He has half-decent proof to back it up
2) The-J has admitted to me that he's a BH and I don't give a flip about anything else.
Eruantien may or may not be a BH. I dunno for sure. But The_J is 100%, incontrovertible, self-admitted black hat. That's where my vote is going and why I'm happy to lock the feck out of my vote, and possibly have a beer.
