Just recently, Pokemon GO players were surprised with the recent bans Niantic implemented. Most, if not, complain about getting banned without even knowing why. It was revealed that the studio is going after cheaters who use unsupported third-party app and/or software, as well as those who broke the game's Terms of Services (TOS). But along with those lines, there were reportedly fake emails being sent out, adding to the overall confusion.
According to Heavy, Niantic started sending Pokemon GO ban emails -- all legitimate -- on Thursday, August 18th. The emails were basically about letting players know that their respective accounts were terminated.
The Pokemon GO ban implementation - be it permanent or a soft ban - can be a result of anything from using third-party applications and/or software to utilizing GPS spoofing tools to breaking the game's TOS. Below is the email the company has been sending to the affected users.
