Some of the groups around Asheville were "eco villages" that could get rather culty, including the kinds of high control abuses that occur in cults. All groups weren't like this but I recall hearing some crazy stories involving shaming people into giving money to the group (while the higher ups are "more equal" than everyone else) and sexual exploitation.

There was one case where the group leader/organizer ran away with a bunch of cash, and one or two people tried to sue but they'd set up some kind of shell company structure and had conned people into signing things that made it hard to sue or press criminal charges. I think they also left the other members on the hook for a property lease, since the things they'd been conned into signing did that too. It looked a lot like an explicit long con targeting the hippie trust fund kids that would come around. Sex abuse too apparently.

I heard more than one story that mentioned members of the Hells Angels, at least allegedly.

This is another aspect of small insular communities in the good old days that the trads and anarcho-primitivists (left-trads) don't talk about. It still happens in small communities today, but a lot less due to the presence of larger scale nation states with laws and law enforcement. If the sheriff in your tiny rural town rapes you, you could try to bring charges at the state level or at least sue. Worst case you can move, and with a global money system you can sell your home and take the cash with you. Without that larger context, there is no recourse. If your local tribal chief, town sheriff, or cult leader wants to take your stuff, pressure you into polygamy, or rape your kids, there's nothing you can do about it. Back to nature!
