After a hiatus that led many to suspect that Mark Cuban's ShareSleuth experiment had gone the way of the hula hoop, Chris Carey is back with a scathing report on China Fire & Security Group Inc. (NASDAQ: CFSG), which bills itself as a "leading total solution provider of industrial fire protection systems in China."

The ShareSleuth report found evidence of the usual suspects in pump and dumps: exaggerated resumes, disclosure issues, associations with characters of ill repute and a lot of hype combined with little evidence of a strong operating business.

Another major red flag: CEO Brian Lin told Mr. Carey in an email "that you should be careful since you don't know how strong our business is and how many big deals we are close to completion. CFSG SHORT SELLERS WILL BE SQUEEZED - SOON!!"

An email from a CEO to a journalist of that nature is highly irregular, securities lawyer Howard Sirota of Sirota & Sirota told me in a phone conversation. He added that it is a violation of Regulation Fair Disclosure, an SEC regulation requiring that material information be disseminated simultaneously to market participants: "It goes back to the concept of full and fair disclosure. That statement wasn't made in a public dissemination to the entire market. This is selective disclosure, an effort to effect the price of the stock by giving information to a selected market participant. The idea of full and fair disclosure is a level playing field. This is like whispering to one analyst 'We're gonna beat expectations."

Be sure to check out this story from ShareSleuth -- the site could develop into a tremendous resource for investors.

ShareSleuth, Mark Cuban's pet project (He calls it journalism) that seeks to uncover fraudulent companies has a new target: Orthopedic Development Corporation.

For those of you who are unfamiliar with ShareSleuth, the basic idea is this: Cuban hired a guy named Christopher Carey to do investigative research into companies that may be engaging in deception and then write about them on the website. The way that Cuban pays for it is where it gets a little controversial: Before the "picks" are posted on the website, Cuban is told about them and he shorts them. This is all disclosed on the website, and Cuban bills it as a new type of financial journalism.

While I don't have any problem with what Cuban and Carey are doing, I'm not so sure it should be called journalism: Journalism is paid for through the sale of publications and advertising. ShareSleuth is more reminiscent of the work of Manuel Asensio, an investor who put out research reports slamming stocks he was short.

The site received a fair amount of negative publicity, and its latest pick differs from its first two picks, Xethanol (AMEX: XNL) and Utek (AMEX: UTK). Orthopedic Development isn't public and, as such, Cuban has no financial stake in the company. The choice of a non-public company may be an effort to appease those who complained about the supposed conflict of interest in the earlier picks, but I'm not impressed.

The problem with exposing a non-public company is this: Who cares? There's no way that we can seek to profit from the expose, and it's just not very interesting. Public fiascoes are much more fun to follow.

Meanwhile, Mark Cuban is writing about his colonoscopy on his blog. That could possibly be less interesting than the piece on Orthopedic Development.
