Rampant cheating ruins this game

There continues to be rampant cheating that is ruining this game. The cheaters ruin it for the rest of us that actually get out there and play. The most common cheat now is players that have multiple accounts and go around taking 2k off a gym then add back to it with their main account, kicking off their own teammates.

We used to be on the gyms around us, but weve all been replaced by these players with multiple accounts. Niantic, what are you doing about the cheaters??
