I had a website that was built for the previous owner 11-12 years ago and I get a demand letter that I pay for copyright infringement on a single image. Of course I don't have the info from the image and the web developer that made my site is long gone so I don't know what account or email the image is registered under. But they probably know there is a good chance someone isn't going to have that info 10+ years later so they hire a company to spray and pray copyright claims at every instance of the image on the web hoping they pay the settlement.
