Hopefully not, I think it is worth a try, the people currently inside the ecosystem probably won't exploit the system but I guess down the road when the new user of the previous new user is refffered, we won't know their intentions. Worst case scenario, stop giving money when it does happen. And also the fact that you only get 10 LEO is the users is not active is a good thing. You have an incentive to bring active users that will make others buy a subscription to #premium.
