I've seen it a lot lately. We don't allow a directory listing view of our site, but I've seen them almost in a spidering style. One right after the other.
I have a little FB widget that shows what pages have been "Liked" or shared and interestingly enough those pages or images that they are accessing aren't shown as a human "like"
