I'm just waiting for the sweet day when I get vigilante. Hell, I'd murder the lurkers as the serial killer, just for the satisfaction. I could claim vig when I eventually hit mafia and get instant mega town cred...
Seriously though, lurkers have lost almost half the games I've played in for town, either directly or indirectly. They do us a disservice if they're town. If you're going to post once per day and make a vote, you're not actually playing, and you'd get the same experience from letting somebody else play in your spot and just watching.
If you find that you can't manage to be active and contribute, get yourself replaced so that when lylo comes it won't be one active player getting run around in circles by the entire scumteam.
