On one hand, bragging about the purchase was a pretty stupid move as it almost certainly would rub some people the wrong way. On the other...these gold sites don't stay in business because one guy buys his epic mount. I don't have any hard evidence to back me up, but I would guess thousands, if not tens of thousands, of people buy gold everyday. Perhaps gold buying has become so prevalent that people just don't think it is wrong anymore.
I have never bought gold myself. I don't really look on it as the worst offense imaginable, but I don't think it is exactly playing fair either. Have you ever bought gold? Know anyone who has his Visa card on file at a gold selling site? Are you ever tempted to buy?
