The insiders are admitting that it's a pump and dump, in order to absolve themselves from liability. It is "standard language" because that's what all penny stock insiders do in order to get away with what they do for a living. Their victims, penny pumpers, don't care about stuff like that. They just operate on the "bigger fool" theory, and on a message board, they can be anonymous, thus avoiding liability, while they try to find someone to pay more for the worthless stock than they did.
Liberty Star is no better or worse than thousands of other pump and dump schemes.
