I have 463 out of 4360 players banned
This is prime only. I have a second account to test out non-prime as well, and let me tell you, there no one is even hiding it because they can just get a new account and play competetive within one hour by leveling up to Rank 2.
Right now from my experience:
Prime: 1-2 cheaters in one game (if you soloQ)
non-Prime: 2-4 cheaters in one game (if you soloQ)
