alot of images of items now come up with an addy you can send btc to.."quick buy" or something.... but yeah its a scam. looks like it was made in mspaint.
I think the theory is people have figured out howto replace images on the site using sql injection of sorts.
At first it was just happening to the top sellers, but now its slowly happening to all the items... when it happens the seller has to re-list the item otherwise the postage options don't work.

But it's ok, Bitcoins aren't "real" money.
Hope this isn't the final straw for SR. Now that they are going to lose people's confidence since they're going to be the target of future hacks as well. Or at the very least very many attempts.
