From a source:

I’ve heard there’s a documentary crew from HBO max and there is a trans female going through recruitment which is the reason behind the doc – getting mixed opinions on that as you would expect in Alabama. I also know that UA Panhellenic would NEVER sign off on that. There has always been a heavy media presence during rush week, especially since 2013 and there was a race debacle that made national news. I’m not sure if these are just out of state ppl that don’t know the media presence and think it’s docs or if UA Panhellenic (and every single chapters’ alum advisors, AND national boards) did the absolute unfathomable. Because I could never see the sororities opening themselves up for national criticism… again.

They can control their social media presences. They can’t control a documentary.
