I'd bite and see what they at least claim to have, but have yet to see someone offering first hand. You are right, considering how tight her communication network seems to be now, its unlikely she will sell nude customs to just anyone without dropping a ton of cash first. Buying from resellers might be less risky.
I've contacted her a while ago and tiptoed around the idea of her doing anything even slightly NSFW and she straight up rejected it. Maybe someone has to build rapport with her by requesting SFW customs then slowly get her to do NSFW customs. She probably has distrust because her buyers leaked her private customs
