The issue is not whether you voluntarily shared something sensitive (i.e., personal secrets, nude photos, etc.) But if (as alleged) you are later blackmailed, threatened, etc. with that material.
Actress Catherine Oxenberg was quite desperate to try to get her daughter out of this group. There are definitely issues where an adult (e.g, her daughter) denies there is any coercion and says she wants to stay in, but from what I read there are possibly criminal tactics being used.

Ohhhh... that must be why so many women are prosecuted when they are intimate with a man, or have an affair with him, and then use it to threaten and blackmail the man. Oh wait.....
