<human>: Can you condense the text into a few key points?

My roommate is really excited about this site:  (Not promoting, just giving reference)
I asked about it when I got home and overheard his sketchy call to some dude who, as always, is offering him quick money online.

The site is about trying to refer other people into becoming members of the "work at home and make $300 a day" by completing one offer. According to him, he gets $20 every time his referrals complete one. He has a website set up and is posting on craigslist.

I tried googling, just didnt find a posts that explains how this scam works or how he would be scammed. Can you help me prove to him what his doing is not easy money but a dangerous scam?
<bot>: My roommate thinks he found a magic way to make money online, I believe its a scam and need help proving this to him.
