If you thought that YouTube was mostly a way to discover lame-o fan trailers, not-so-sophisticated movie spoofs,  or the latest viral video sensation, think again. As ArsTechnica reports, pyramid scheme recruitment videos are now flourishing on YouTube. Although these so-called "cash gifting" or "cash leveraging" schemes are often referred to as Ponzi schemes, they're different. As an ArsTechnica commenter pointed out, in a true Ponzi scheme, early joiners are "paid back" by money from later "investors" by the people controlling the alleged investment, but in a pyramid scheme, you make your money only when you can con others into giving you money.

Regardless of how boring your Friday afternoons might be and how desperate you might be to make more money, watch out for videos like these. Our advice? Save your cash for better investments, like more RAM.
