I know some people who have done it, and some of them have made money. But I'd stay away from it if I were you.
It's your typical multi-level marketing scheme. It's not a true scam, because you can make money and they will pay you. However, your potential is typically very limited. Once you've run through your circle of friends and social contacts, who are you going to sign up? And if your friends on Instagram are already doing it, then they've probably chewed through a good portion of the market share that you would have sold to.
These things are (potentially) good if you're the first one in. But the more people you know that are doing it, the less you'll be able to sell. And ultimately, you just run out of people to sell to, making it a poor long term investment.
