Certainly the docker repositories are vulnerable to this. If you look at a users' profile page you can see the download-count for each image. The biggest download count becomes the most popular image, and you can script it trivially: docker pull skxskx/wordpress docker pull skxskx/wordpress .. docker pull skxskx/wordpress It's not something that I regard as a problem, but I did notice in passing and added 50 downloads to a few of my images on evening to test the concept.
