I agree with the last dozen or so posts. Sorry to pick on you geekline, but auction terms like that turn me off faster than bad photos do. I don't expect sellers to let me dictate terms or to "put up with my bull", but I do expect them to be polite, and to respect their customers. I understand that sellers deal with a lot of trolls, but assuming from the start that your customer is a troll is just setting yourself up for it. "The best defense is a good offense"? Not in Customer Service. Sorry.
Of course, on the other hand, it's your auction, your terms, your right to write them however you like. My right to disagree, and my right NOT to bid. I'd be curious, though, to see if your average sales price or bids-per-view went down after you added those terms.
