Hello, the mon you got wasn't hacked, I'm a member of their discord. They also send out other pokemon such as 6iv shinies with the link name. The shinies are caught in their 24/7 6iv shiny raids which are free and available to any member of the server. The other ones such as Kubfu which is shiny locked are simply obtained in-game and duplicated via the god egg as well as the master balls. Hope this helps 🙂
