I can remember that did that kind of thing back in the 70s and 80s. Scientology comes particularly to mind but the moonies and ISKCON used to do things like that too. Scientology people would approach you on the street to take some kind of a free intelligence test or something like that.Alot of weird scams like Amway and other pyramid schemes would also take similar approaches. It's the tactic of con artists.
Back then DLM really was more ethical at least in the sense that people always knew what they were getting involved in, if not always with all the gory LOTU details. Even in the most polished situations it wasn't really that well hidden.
At least it terms of recruiting the cult has gotten alot more deceptive and sneaky. Personally I don't care what it is someone is trying to sell, but that kind of deceptive marketing is really unethical and downright sucks.
If any premie is reading this, take a step back for a second and ask yourself how you would feel about being victimised by this sort of tactic. You lull yourself into thinking that you are helping people and blind yourself to the blatant fact that you are pulling off a cheap confidence trick.
And I have to say, I wouldn't buy anything that I was being tricked into like that, no matter how good it was.
