They spend so much time trying to keep cheater out that they forget about regular players. With all the crazy security supposedly to keep cheater out, turn out just keeping regular players have access to the game. Gym keep having this rubberband effect and the capturing system is totally random. They have items that supposedly effect the rate of capture which it does not.
After a year, they still cant get the server to stabilize.
