It's a new advertisement that appears as the 2nd post on any page of a given thread. It's made to resemble a forum post, as opposed to a typical ad. The poster is CurlyGurus, and the post title is "Check out these links for more information." Unlike real posts, the background on this is light pink, and the only content is links to products or videos related to the first real post prior to the ad.
