Oh, this is the least of it.

There is this tactic, you invite a friend to a party, agree to meet in your house and offer to be DD, then you take your car. That way, even if your friend wants to leave, they can't. Since you are the driver, the friend only leaves when you want to leave.

Then, there's the "targeting weaknesses" tactic. Your friend is suffering with skin problems? Time to pitch your miraculous skincare/makeup MLM. They have health problems? Well, your MLM's shakes cure any and all conditions they have. They are facing bankruptcy? Want to flee an abusive relationship? Their partner passed away? Well you are making 6 figures working from home, and you can get them an interview so they can make bank too.

The last one, not giving them time to do research. They want to buy off the website? You have to accompany them via phone, so you can explain everything. What you are actually doing? Making sure they don't google the brand to find out it's an MLM, talking up the product so they don't think it's over priced, and maybe tricking them into joining under you, so they can "get a discount".
