>>29080242Whales are the mobile gaming term for people with money. They are the ones who spend the most on "free" games, the big targets for the companies. Making them happy is typically higher priority than game balance in crappy mobile games.
A whale can buy lucky eggs and run them constantly, even while just moving around hitting Pokestops. They can always have a full box of incubators. They can use lures all the time while popping incense. They can buy pokeballs when they are out again and upgrade their lots to max without breaking a sweat.
In short the game is broken for them and very easy so they level faster than everyone else and have more stardust and more hatches than everyone else for bigger, better mons.
Bigger mons that sit in the gyms and collect more stardust and coins for the already wealthy whale.
Add in the lack of spoofing protections and it goes from problem to game-breaker.
