Let say x, y and z are the power puffs and a, b are the two known scum.
X and Y can just vote anyone besides a and b, and say I'd really like to vote for a but c will do for today.
And the powerpuffs can ALL repeat this exact sentence with one of them saying b instead of c.
Scum can do a similar thing, but they're only two so it doesn't work.
If the powerpuffs do that (as regular townies have no incentive to) it outs two scum and I guess the powerpuffs, but thats a 3 for 2 trade which you'll take every day and then you have a LOT of time to guess the one scum.
