What you have described sums up exactly the predatory nature of Multi-Level Marketing.
People are led to believe they could be making a new friend and boom, turns out all they wanted was you to join the cult, it is despicable behaviour.
I hear stories constantly of people who have moved to a new area or stay at home parents who are looking to make new friends and are constantly being subjected to these vile solicitations.
When you tell them you are not interested they suddenly seem to lose all interest in you.
