Nude celebs here
This page is probably just one example of people doing this; it’s the review of Wondercon by the folks at SFist. It features some info about appearances by Elisha Cuthbert, Christian Bale, and Joel Silver. If you look at the file names they used for those images, they are elisha_cuthbert_naked.jpg, elisha_cutherbert_nude.jpg, christian_bale_naked.jpg, etc.
If you are just reading the page normally, you won’t see that. But I guess if you are a search engine, you are going to collect that info and of course rank the page higher. Kinda cynical thing for a supposedly legit site to do. Maybe it’s standard practice.
