Yesterday in the mail, I received a 20-page advertisement from Tobin Smith, who claims to be the founder and CEO of NBT Equity Group, Inc. He's also the editor of Changewave Investing and is the founder and chief investment strategist for Changewave Research.

Tobin is currently promoting a stock called Petrosonic Energy (PSON), and this advertisement is being mailed out to thousands of investors right now.

On the front page of this advertisement, the headline screamed, "Oil Tech Game Changer! This Breakthrough Technology Could Make the Next Four Years the Most Profitable of Your Lifetime!"

And on page 5, Tobin made this bold prediction: "Buy shares of PSON around $1 right now and you could . . . Turn $10,000 into $50,000 in the next 6-12 months!"

Then on page 12, he says, "And if China were to buy sole rights to the technology for a mere $2 billion, each of those shares of PSON that you can buy now for around $1 could be worth $30.95. That's a gain of 2,995% and it could be enough to . . . Turn $10,000 into $299,500!"

Finally, on page 18, Tobin screams, "PSON in ready NOW . . . and working TODAY. That's why I'm so excited about PSON . . . it's ready to make its big move NOW . . . I urge you to load up on PSON NOW! And I also hope you'll want to keep up with my next great finds as a Charter Subscriber to my Next Big Thing Investor newsletter!"

Then he asked me to send him a check/money order for $79.00 to receive 12 issues of his newsletter.

However, on page 17, I noticed this disclaimer in small print: "Changewave Inc. (dba NBT Communications) is paid fifty thousand dollars as an editorial fee from Beaumont Media LLC." (It sure is weird how that particular sentence was buried there in tiny print, as if he didn't want me to see it.) And remember, Tobin is the founder of Changewave.

It appears that Tobin was paid thousands of dollars to promote PSON. So, why would anybody consider this to be legitimate investment advice? An honest stock analyst would not be paid to promote a risky penny stock. Some people will say absolutely anything as long as they get paid to do so . . . and if you lose money, they don't care.

In addition, if Tobin really thinks that this stock will go up by 2,995%, then why is he asking me to mail him a check for $79.00? Why doesn't he just forget about me and buy up the shares and make himself extremely rich?

Just think about all of the paper that was wasted to mail out this junk. I wonder how many beautiful trees were chopped down for this. And I wonder how many people are actually going to buy this stock that he's promoting.

So, if anybody else gets this advertisement in the mail, throw it in the garbage immediately.

And whatever you do, DON'T buy PSON or any other penny stock that Tobin Smith promotes in the future.
