I can see that every post in 9gag has "9gag.com/UserX" somewhere, even if that image was seen in other part of the web months ago.

And Memebase is updated regularly, but because they have many subpages, their new content is derived to them, leaving the homepage with the highlight. When 9gag uploads 10 new posts, Memebase uploads 3 to Art of Trolling, 1 to Superheroes, 5 to Comixed, 1 to Picture is Unrelated, and 3 of those images go to the homepage to be highlighted.
