given that the cop won that game, I think i'd be fine anyway
And given that mina deemed me responsible enough to give me the IC seat of this game, I might as well digress in some theory discussion. And why not on scum play, one doesn't hear about it all that often, MS as a whole likes town better and scum tend to worry about giving away their secret plans and get caught. So all theory stuff in the wiki or MD is mostly from a town perspective.
I fear I've since lost the article by Thestatusquo, it might even have been made during one of the rewinds this site has gone through, but it contained an idea I've since seen a truth in. As scum, your goal isn't to play like you are town. You'll still be "acting" and it will never be the real deal. You might get it right to 99% (though I'd be surprised) but even then you'd get lynched more than when you are town. That cannot be the point. Your goal should be to roleplay "super town". The guy you could not hope to be when town. Just reasonable enough, just nice enough, harsh when it matters, having the right friends, the right enemies. You want to roleplay the guy you wouldn't think about lynching. Forget meta, unless you play with the same people a lot, MS actually hates arguments about it, and only a few players are really interested in it. So why bother playing like you do when you are town? Your audience won't even notice!
In stead, give your audience what they want. Get to know them a bit, think of what tells they think are scummy, what tells they'll see as town, and give them what they want to hear. They want that just about active player, who's post are meaningful (experiment with this, lots of posts make you hard to lynch, also makes hard to get points accross), they love someone who pushes and asks questions, but who's moves they can understand, things they would have done themselves. All townies are lonely. They just want that friend that understands them. And who'd be a better friend than you?
What you do in the end and how you play it is up to you, it has to fit your person and style. But make sure you have a plan, a general idea how you are going to fool the town this time. Most bad scum are the ones who sieze up the moment they see that red role name in their role pm, and worry about every post they make, trying to achieve a strategy they cannot hope to manage (playing like they do as town). The difference is a matter of mentality. You can try to avoid everything, which is a negative approach, or you can try to fool your opposition, an active approach, setting the game to your hand. I'm a big proponent of the latter.
Surrender, imagine and of course wear something nice.
). Yes the game can be a drag, people can be wonderfully annoying, but it's a game after all, play it as such. Try to win, even if it seems pretty useless. Outside of the game the same people who pissed you off in game are often very nice, and you want to be able to talk to them again 
Maybe we can figure out with the town if it would help or not.
