Why we get bored in this game sometimes?

Before when the game started I'm so excited specially on GYM battle. The Gym color change almost every hour. But as of now the GYM are all held by one spoofer team with L10 Nurse. And its like a month and almost all GYM are untouched. Maybe some team got bored to take it down because they have to travel and battle with it then a spoofer team regain it back without visiting in a near area where the Gym actually place. And its hard to deal with a L10 Nurse Gym because besides from a tough defender, it also have an issue with Lag, Battery Temperature and Playtime. Just like me... While seeing those GYMs untouched by weeks or even months, I felt bored. But because of being a fan of PoGo. I'm still hope that the game developer will improves the games and can take down cheater too...
