A high kd isn’t too suspicious. Most streamers have very high kd ratios so it’s not a big deal. With that being said, they still die. If you are surviving every single raid and your kd goes way higher, for example 25+, then you might start to get flagged or watched. They could just be waiting for your account to just use auto unlocker or something that makes a big break in code just once so they can ban you. Personally I had a 13kd before I started cheating. In the teens isn’t too rare.
