If it's a proven fact that one can get a Rep that they see on a TD site here, why wouldn't you do that instead of taking a chance of throwing away a couple hundo?
Yes, some are not always a scam, but why risk it? Is your money not hard-earned? Can you just burn $$$ in a fire and not care? More power to ya, but I usually want to get what I order and not some brown-bag mystery gift.
