Ellesclub. Mickelwait had spread this claim across a few of her Twitter accounts that Ellesclub was a trafficking victim and was underage in the videos on PH at the time. Most of the proof she refers to doesn't actually exist, though.
The most concrete proof she's put out was Elles' stated age on her social/content profiles. Because apparently Mickelwait can't think of any reason why a pornstar's bio would say she's been 18 for ten years straight.
