I think it's important for people to know these two are offshoots of Scientology. I don't mean Freezone, but surreptitious secular business that use much of the same "tech" in terms of both mental manipulation and financial predation.
Landmark is not nearly as insidious since Werner left, but it still does some psychological damage and defrauds people through a "volunteer" scheme where devotees donate free labor for recruitment and administrative work pawned off as training. They left France (and three other European countries) in 2004 after a couple of TV expose programs.
Avatar is more insidious. It's an MLM scam that operates sort of like Amway without soap. It even has a top-secret exorcism process on the upper level Wizard course that's a direct knockoff of Scientology's OT III and NOTS. For more info, see www.avatarcult.info/
