I found a particularly egregious case today. This site has mass-uploaded thousands of images on a wide variety of subjects to a blog that is connected to high-following social media accounts. The owner is even cropping out watermarks and (not that it matters) not crediting or citing the sources. The Facebook page has 425,000 followers and the page is advertising with both Adsense and Taboola.
whitewolfpack.com
The site has taken so many images that it's impossible to just scroll through to find one. If you search for specific storm-related terms in Google Images, you can locate images. For example, I saw chaser images using these search terms:
whitewolfpack.com tornado
whitewolfpack.com lightning
Of course, the user is hiding behind an anonymous domain registrar and provides no contact information. The good news is that any one whos image was taken can report the site to Google Adsense and Taboola, if two or three reports are logged, the site may lose its advertising accounts:

For Taboola, email the URLs of the stolen image and the orignal to
