The only legal requirements for limiting selling apply to officers of the company and other such persons in control of the company. If you don't fall into that narrow category, then you are pretty much free to do what you want with your shares.
The problem FITX might have, is that the shares for these people were so cheap when they were awarded, that selling is going to be an attractive option. Very attractive.
That HHS Group, a promoter, was handed a total of 8% of FITX for services and I believe they paid debt. Still, those shares were awarded at the low low price of fractions, 100ths or 1000ths of a penny. What would you do if you were holding that kind of money tied to company that has never seen black ink, and is run by a lawyer that couldn't run a profitable law practice among 4 or 5 other losing ventures. Just going off what I've seen posted here and what is sorely lacking from the resumes of Billy, Jeffy and Sammy . . . Successful businesses.
