My friend joined an MLM even after I've talked with her extensively about them. Awhile ago, her mom got into MLMs and at the time I voiced my concerns to her. I linked her to many sources about MLMs and explained I was concerned her mom was being taken advantage of. She vowed to keep an eye on her mom. 

A few weeks ago the same friend invited me to a colorstreet party. We had a chat shortly after where she assured me she was not becoming a colorstreet consultant and was just hosting a party for a friend. I was relieved and left it alone. Since then, her Facebook has been nothing but colorstreet ads and one of her most recent status updates straight up admits she is becoming a colorstreet consultant for "extra income". So she lied to me. I feel pretty hurt and I'm not really sure if/what I should say-- she's my best friend from college and I'm really bummed she lied to my face.

Fuck MLMs.
