How do you handle an acquaintance whose only motivation is to get you into networking marketing or MLM?

About 2 weeks ago, I met someone who worked in my building who recognized me from Facebook. He said he knew my fiancee so we chatted for a bit. I gave him my contact info and a few days later he called.

This morning he left a message on my voicemail wanting to have lunch with me. He also left me an e-mail a few hours later. Why is he so interested in my friendship?

My first instinct told me that he was trying to get me into "multi level marketing", similar to Amway and other pyramid schemes. I went to his Facebook page and saw a bunch of links to domains he created, and they were all selling/promoting a health product.

This situation is similar to experiences I've had with MLM types. It seems like they have this distorted view of reality and won't take no for an answer. They never answer skeptical questions and insist that you either listen to a DVD or attend a meeting at a hotel to find out.

I have always ignored them and they eventually give up.
