I'd suggest that the next thread is posted for host to post rules once 12 players are still alive. With one player dying every 24 hours if things are sped up, that leave about 6 days till mafia ends and then next one begins. If people are dying every 48 hours, that's 12 days but last 6 days will have only 9 players, at which point it's usually simple enough to get scumtells. e.g. Sub's mafia where last mafia have been obvious for quite some time.
