I confirm that not everyone who has a 7-9 star team is a 'cheat'. In fact, many of those users have such teams because they are able to complete a lot of offers due to being in advantageous regions. Some users can earn as high as 50-100 green packs per day. I myself, despite having no offers for my region, I have planned to start building such a team at the end May - start of June of this year, where I would have reactivated my other team (Virtual F.C) and would have made an initial investment of 1350 tokens but changed my mind after seeing some non-desirable things in this game lately. So, there might be other users out there who will put in a lot of money in this game to build their team.
