Most if not all GMO seeds are contract grown and the farmers that plant them have to sign contracts with the creators stating they will not sell or share seeds with anyone or face huge fines. It's doubtful anybody is sharing these seeds unless you are a related to the person with them or a best friend with them that they trust can keep a secret. In most cases farmers can't even save seed for themselves and have to get new seeds every year. It's a trap that many farmers fall into and then can't get themselves out. If you have doubts just stay away from corn, soybeans, cotton, sugar beet, wheat, rice, or Canola seeds from the trade in question.
