Got many delta server errors after using chear engine

I don't know if it is because ubi's anticheat system or just server problem, I got countless delta error while playing this game.
After manipulate the fire rate and ammo and playing about 15mins, game suddenly just freeze and crashed or got a loading circle and got an delta message.
It happens since a few days ago when the first banwave start. Luckly I didnt ban yet.
Is it the pre-caution of ban?

Same. Got Mike error after using rapid and no recoil hack.

Did you exaggerate with the hacks? I only use ammo lock and RPM on only one gun. Dont use it for all guns you have equipped.
