I can't find an IMDb page for the following documentary miniseries that just popped up on Netflix (so... I can't get too much context beyond the trailer they have for the show on the streaming service) ... but is the Family cult discussed in this series the same as The Family exmember survivor's group here at a2k?
Easiest way to look up COG (also known as XFamily, which are one of the groups here) is to look up flirty fishing and boy oh boy you don't really want to know what that means.
