It does get a little tiresome. I mostly just skip them, unless there's something else about the image that interests me. I can't really complain, though, since I never post. I do, however, enjoy seeing images that I can learn something from, even if it's just a cool texture on exposed skin. In the meantime, I just figure that art is subjective, and even if a lot of the images aren't my cup of tea, they're apparently somebody's. If it makes the artist feel good to submit them, that's dandy by me.
