<human>: My ex just posted on her facebook status that she got a job at *Vector Marketing* and she will be selling knives.

Now for the people that don't know about this, this is a major scam. You pay upfront for a set and then you are to sell it. But the problem is that no one buys it. 

I want to tell her that she is about to get trolled but I know, if I try to explain her the situation, she will think that I am just trying to put her down. And I don't want the world to witness a scene on FB where she brings up some past bullshit just to make it seem like I am against her.

Although, I have decided not to, Should I rain on her parade?

<bot>: Ex thinks shes got a job but its a scam. Should I reveal the bad news to her and get denial crap OR just let her learn for herself?
