Nobody likes a scam, when we're the ones being scammed. But from the outside looking in, sometimes you have to respect a scammer for their courage and effectiveness, especially when their intentions are good (or at least understandable). The "act like you belong" community on Reddit is devoted to posts about people who cheated the system by pretending to be someone they're not. Turns out, you can get away with a LOT by simply acting like you're someone else. They key, apparently, is blind confidence.
