"adult sexual exploitation" usually refers to revenge porn, but it can also refer to threats of rape. Here's my guess as to what happened. Somebody posted a joke that was, taken literally, a threat or incitement of rape. "I hope you get fucked and don't enjoy it". An admin of the group "liked" or commented on the post. Later, a human labeler determined that the post was "adult sexual exploitation". It was removed. Because the admin had "liked" or commented on it, the group was automatically banned. That's FB's public policy on "adult sexual exploitation". Just a guess, but that is the most likely explanation to me.
