Don't forget the securities section. There are 101 scam attempts for each legitimate thread. Some of them don't even make an effort. I scooped up these "securities" off the first page and not one of them is even remotely resembling a legitimate offering. It goes beyond being "embarrassed" to wondering why nothing is done to discourage the practice.
Ah, but there is! The forum provides a helpful warning:
"Warning: Moderators do not remove likely scams. You must use your own brain: caveat emptor. Watch out for Ponzi schemes. Do not invest more than you can afford to lose."
