Friend was brainwashed by MLM-/ponzi investment scam. What can I do?
The title of your question basically asks: What can I do? And you state this regarding the meeting and “advice” they gave towards criticism of their method: While this they also indoctrinated that you should avoid talking to   people talking bad about it (or say it is scam) because you gain no   money from them and they just want to destroy your business. First, you really cannot do anything to “save” your friend if they have bought this nonsense. You are right, it’s a scam. But past stating as such to your friend, there is not much you can do past shielding yourself. The reality is this: Any scenario you are in where you cannot ask basic questions and get a reasonable response or are given—at least—the option to walk away unscathed or uninsulated is basically a cult-like mentality. Simple as that. If the first thing someone tells you is “Don’t listen to others, just listen to me…” then you need to excuse yourself to go to the bathroom or something and just leave. From my personal experience meeting people who are successful and have power, they always—and I mean always—ask questions and are critical of things they invest in… Whether that investment is time, money or just basic mental energy. Rich people are just like you and me! Except they have more money so they can take bigger risks. Critical thinking and the ability to walk away from something are key life skills. Now others have talked salesman psychology which is on point. But here is something else you brought up in your question: He also wants to use his position as respected member of multiple   local youth and other communities to get their members as referals or   in his words “…to give them the oppurtunity to also simply earn   money.” Okay, so you can set personal boundaries between you and this clown, but you cannot stop him. But if he plans on targeting people and organizations in your community, you can warn them about him and his behavior and this scam. Chances are other people will know right away it’s a scam, but honestly if you feel the need to help others, that’s the most reasonable thing you can do to help them. But whatever you do, don’t take any of this emotional crap personally. If anything, maybe you can learn some reverse salesman techniques to get this “friend” to disengage. Such as only meeting with them in public and if they say something really vile to you, repeating what they said back to them as a question… Maybe even louder so everyone can hear. Remember a harsh reality of life: Public shaming can work to change someone’s behavior but you never want to do something like that unless you have utterly no choice. That last bit of advice is pretty harsh, but the reality is at some point you need to do something to “smack” reality into the situation.
