I don't think BiPolarBob is a scammer. He even tells us not to trust him in multiple posts. What kind of scammer tells you to watch out for him? Then again, anything is possible, but I think that BiPolarBob is a nice guy.
Double bluff? I don't think he's a scammer either but it's not uncommon for scammers to try give people a false sense of security or make out like they're doing a good thing or are a good person when their motives are the opposite. Seen a few scammers on here make out like they're scam busters themselves which they do to try get feedback or appear trustowrthy.
