In a blog post, Niantic said it issued sanctions to players across three games - Pokemon Go, Ingress, and Harry Potter Wizards Unite.
It said since 2020, more than 20% of those were permanent bans.
"We have made a commitment with all of our players towards promoting fair gameplay...and improving transparency with our players," the creator wrote.
The three popular games all use augmented reality to combine gaming with the real world.
How does the cheating work?
