High yield investments

I use gmail as a backup account and one of the ads on the sidebar caught my attention. It almost sounded too good to be true! EIMTrust - "True Diligence". They can turn your $1,000 dollar initial investment into $8,000 in only 72 hours! If you invest more, the percentage increase is even higher! Wow. From the website:

"IF YOU INVEST $10000 YOU WILL RECEIVE $400000 IN 72 HOURS
IF YOU INVEST $50000 YOU WILL RECEIVE $9000000 IN 72 HOURS"

etcetera. Amazing. I tried to figure out how they do it, but there are lots of big fancy business words sort of strung together in an unintelligible fashion. For example: "Our team of Managing and Strategic Directors, supported by our Venture Partners and Investment Professional, provides entrepreneurs with a rich base of strategice, operational, technical, and financial experience, and an extensive local, national, and international network...." and so on. So I couldn't figure it out.

By the way, they are so busy that they're not taking phone calls right now. And they only accept gold bullion.
