Seems like the frauds find new ways to "branch out" all the time, niches within niches. For example, I posted part of an article a few months ago that mentioned someone is now claiming to channel Castaneda (long ago proven to be a fraud) from beyond the grave.
The trend of exploiters preying on Latin American NDNs is newer, maybe 10-12 years old compared to 35-40 years of posing as North American NDNs. I'd say it's driven by the desire to avoid protests and seeing US NDNs as "not primitive enough". (AIM and others spoil the fantasy for wannabes.) Latin American NDNs have fewer resources to protect themselves, and sometimes bigger problems in places like Colombia like avoiding being killed by death squads.
We did post a long time ago on a fraud, Credo Mutwa, who worked with Roy Steevensz ("Littlesun") who passed himself off as a Zulu healer but actually imitated old Disney movies. And there was a white woman passing herself off as a Voodoo priestess, plus an Irish plumber who passed himself off as a Tibetan monk, and Marlo Morgan's "Mutant Message Down Under" hoax. But since this group was founded by NDNs and is focused on exploiters who target NDN traditions, that's what most of our research and discussion is on. I'd like to see more people who from these cultures, but it's not easy. We did have a Native Hawaiian member who we haven't heard from in awhile, plus a Siberian member, Sarangerel, who passed on.
