Yea, I can't really do anything about it because I don't have any sort of watermark on the picture. I looked into the eBay rules, and in order to report a listing, the person has to have stolen the pictures from your auction apparently, and I haven't had any pictures of my car in an auction, so I don't think I can do anything. I guess it isn't doing any harm, but nonetheless it is still not right for him to use the picture.
I guess I'll have to start watermarking my pictures from now on, as much as I hate looking at other people's pictures with watermarks... Oh well, leave it to one person to ruin things... I knew it was bound to happen sometime.
...maybe he should post pictures of his skirts instead of someone else's
