My parents, bless them, are two of the biggest idiots when it comes to MLMs. They have been scammed not less than five times already in the past decade. It even came to a point where they used my name (and my two other siblings' names) so they can have more accounts under one MLM. Now, whenever they talk about an exciting new "business prospect" I immediately shut them down and tell them I will disown them if they ever enter another MLM. Thankfully they have stopped supporting MLMs for two years now.
