This question leads directly to why you must read the SEC filings for any penny stock that you intend to buy. If the company management lie in their SEC filings, they can go to jail. The SECFilings tend to be very truthful about the prospects of success for the company, any usually clearly describe why the company is unlikely to succeed. On the other hand, the major shareholders can pay third parties to issue promotional material that makes wild claims about what could happen in the future, while making sure they don't lie about factual matters related to actual events. A well run promotion does not break any laws!
Read the GNIN SEC filings,and then read the promotional material and disclaimers, and you will see what I mean.
