You mentioned something interesting, mate. Considering the precedent of people being reported trying to sell their teams on Facebook, many of those countries probably have communities that farm teams to sell. If it happens in most other online games, most notoriously was "a thing" on World of Warcraft for many years, its not outlandish to think some of those teams were just sold to others.
Again, its my firm belief all these exploits detract players in a greater scale than the activity needed to manipulate generates revenue to Nordeus. But... not my company.
