Auction as Spam Vector
I'm selling an old laptop on eBay, and since posting the auction, I've had 5 "questions posed by potential buyers" that were spam.
eBay lets buyers ask questions about the products being sold, and because these questions could be from potential buyers (and always were, my experience, up until yesterday), sellers need to read and answer these questions in a timely manner. It's not something you can just ignore. So it's an effective attention vector.
They say the spammers wouldn't be spamming if it didn't work, but it's hard to believe that anyone could be in a buying mood after getting tricked into reading spam this way.
How big a problem is this? Anyone else find a particularly interesting spam vector?
