This works great until you realize you're punishing innocent players because of CGNAT and IP addresses getting rotated. Cheaters usually know how to get their router to request a new IP address. That IP address then gets assigned to someone else later.

This scenario definitely did pop up and we would review it on a case by case basis to unban users or make exceptions. However, it was quite rare. Only a handful of reported instances over several months. If our servers were more popular we definitely would have run into it a lot more.

You would need to ban random people and see how many of them report it to estimate the real amount of such errors.
