First, give it a try, even if it is a fire pit, you should be prepared to step on it. In case it's a pyramid scheme, I can get away.
The second is to give up and find a job from friends and relatives nearby. No salary is required, but experience is needed. As long as you have enough experience, you can see at a glance what a liar is and not a liar.
Don't think too much about others. Safety comes first. After all, MLM organizations are rampant and scammers are everywhere. No matter what you do, you should focus on your own situation.
