Sadly I had to start doing this... As much as I hate it. I went through a week where I had contacted many porn sites and individuals who had ripped a lot of my images, cropped off my name, and sometimes sepia toned them and called them their own. A few sites were using them to promote their businesses. I wouldn't mind if people posted some of the images on their site if they didn't remove my name. Sadly I'm quite certain that I'm not alone dealing with this.
