Hmm I don't see this dispute being settled as it is a very gray area. However, I also don't like my forum reputation being dragged through the mud. Considering $15 = 0.03 BTC, I'll make the payment to the user who posted an image of the sunglasses that most resemble what I ended up buying. This is contingent on my negative trust rating being removed.
Deal?
LOL. Probably no deal. Extortion is yet another sign of dishonesty.
