There are quite a few people upset about the recent changes to Pokémon GO. Some have taken to bashing the game via the reviews section on iOS, others are voicing their concerns on Facebook. Unfortunately there are some others out there that took things too far.
John Hanke, CEO of Niantic, has had his Twitter account hacked. His feed is being spammed with various Pokémon messages, which all seem to stem from recent frustrations with the game. Looks like some rough days are ahead for the Niantic group.
