I should have provided a bit more detail in my OP.
He is… sort of a coworker. We both work in the same group, but he works for a different “company” (though “company” is probably not a good term to describe the entity he works for). He is my customer. Sorry for the vagueness, but I am trying to minimize RL implications. Talking to his management about this would be the end of my career.
His wife friended me on FB. I accepted the friend’s request out of curiosity. At least ten times a day she posts Nerium crap. She also brags about the “free” Lexus given to her by Nerium.
I get the feeling his wife is desperate to expand her down-line, and is pushing her husband to help her.
