For me the issue is stemming from something in the connection. I am not as good as you, TDM kd is about 1.9 but if the connection is on my side and I am up against inferior players it will appear to them as though i am cheating. For example walking into a group of 4 of them ghosting all 4, and not dying. I know they had to have hit me enough times to kill me but the game did not register it. On the other hand i have had games where i can not kill an entire team who does not have a single player above a kd of 1.0, and not because i am missing. I come close to accusing them of cheating. I have only ever reported 2 people and that was because they were cheating. One was invisible, and in god mode. The other had every single perk in the game.
Either way you have nothing to worry about.
