I probably could have handled this better
A Spanish language Harry Potter fan site decided to hotlink one of my HP fabric pictures to use as the background for their blog. They got enough traffic that I noticed when I looked at my stats for last month. Did I try to contact them and ask them nicely to stop? No. Did I just pull down the picture so they'd get errors? No. I replaced the fabric picture with new image; red text on a lime green background that said "hotlinking is not cool". It did get their attention and they stopped hotlinking. They do appear to have appropriated one of my images and made their own .jpg with it, but the site is so poorly laid out that it's hard to tell. At least they're not using my bandwidth anymore (not enough of it for me to notice in my stats, anyway).
