Isn’t that doing the Scum’s Job for them? 
Day 1: I think the Patsy Claim would force scum to make a decision- counterclaim vs. let the townies gain a “town” role. It’s really disadvantageous for scum to counterclaim- primarily because much of the Scum roles are power roles, and a 1:1 trade would set that team behind the other scum team (I could see the Mook or the most ‘generic’ Scum member maybe considering the counter-claim, but again- less likely. The fact that there’s two competing scum groups makes it advantageous for the Town to have the Patsy claim, because the town wants to have the two scum groups deal with each other as much as possible. That’s why early on, Town has the numbers game, but also the fact that the two groups are equal. The longer that two scum groups are equal- the more the two scum groups are going to want to prioritize taking other the other team.
That’s why it’d be ideal to try to keep the numbers even, but I see no easy obvious way to know which scum group is which and killing them A,B,A,B, etc. So as a Townie, I’d say lynching the scummiest as much as possible, and if it’s all from one team, it’ll only make that team all the more desperate to want to root out the other scum group because they suddenly have just as much to lose when the town goes down.
That’s what I’m prepared for. Anything more than that- I can’t really think of it off the top. I mean, there’s the basics- you mix your scums up- you put someone in the lurkers, you put some in the super townie group, you put someone in the helpful townies, you put someone in the antagonist townie role, someone in the snuggling role, and then you have them interact with each other and fight and you spread out your votes and try to blend in. But that’s Mafia 101 across the board, and I think you know that too.
Did you have something else in mind? I’m always pro-discussion and I’m glad to see the ball rolling in productive posts at least.
Did the Mods Clarify this or did I miss something. Do the Scum get their own boards? They must if they’re coordinating who to kill and all, or did I miss something here?
-Are you assuming that there are no Scum Boards? 
Did Mafia change really that much since I’ve been gone?
