I’m not finding any reverse image hits for any of OP’s posts, which on its own could mean nothing, but also means that these pictures weren’t posted and circulated around the Internet. It’s not an exact science, but I almost feel like we’re in a “friend posted this picture to Facebook and OP uploaded it to Lemmynsfw without consent” territory. Personally, I’m kind of leaning towards a breach of Lemmynsfw.com’s rule 2 and would not fault you for taking moderator action (and maybe giving the other mods a heads up).
