Why would you post these links of NSFW images here?
Anyways, I clicked through to the site and was not provided witn a significant amount of NSFW images.
Most weren't NSFW, the ones that were were not extreme, and I felt that the disclaimer was enough.
As for the images, I kept a little file of interesting ones, and didn't want to go back and check them all to remember which were NSFW. So I simply put in the disclaimer and pasted.
That said, I felt that they did add to the comment. They give an idea of the variety of different things that could show up in a discussion, and indicate that you would need to separate them out by category.
