I'm pretty sure you're being facetious there, but you shouldn't be.
Message board mafia is a game. Getting better at lying there, reading people there, debating there, it doesn't have any bearing on actual social situations. You might get better at doing these things on a message board but I don't think that's even the case. The problem is that mafia presents a scenario that isn't particularly like things you'd debate about or lie about or read people on in a real social situation.
