Those are the proofs by some people on that sites. I just joined around 15 of this month and have made $65! It isn't a bad investment. I would at first be like you and wouldn't even try to look into the site. However, the thread with more than 25 pages now attracted me. It showed me that it DOES work. I tried it and realized it does! So I wouldn't say it's a bad thing. Your call
