They are brainwashed, very well mannered and very slick. That is why if you have never heard of them, it is very easy to get sucked in by them. The people that try to get you in are nothing more than slick salesman/woman. From my memory they do not mention who they are, just that are doing psychology tests and invite you to have a go.
They are as bad as these salespeople who won't say no until they get a yes out of you.
