I myself have an accuracy rate of around 60-65% and a headshot accuracy of around 15-20%.
But here's the thing: 99.9% of cheaters have 65% accuracy and 25-30% headshot accuracy because it's the safe max accuracy that really good FPS and top players achieve in deadlock. Players might have good accuracy, like 60%+ but they don't click heads and have low headshot accuracy in 15-20%
However, when you have a player with both 65%+ accuracy and 25%+ headshot accuracy, that's a cheater.
You also need to consider the character. The Warden, the Doorman and the Dynomo can easily have a headshot accuracy of 25% or more. They have a low fire rate, a big bullet hitbox and abilities that help them land more headshots.
However, a headshot accuracy of 25%+ on Haze, Wraith, Viper, Bebop, McGinnis, etc. is a clear giveaway of cheating. They have a really high fire rate. If they go for the head, they will have a high headshot accuracy, but a low overall accuracy since they will most likely miss with most of their bullets. You get the idea.
You can't just start banning everyone with these accuracy numbers, since you'll end up banning innocent players who just have good aim. That's why cheaters run rampant and unpunished in Deadlock — they hide behind maximum safe accuracy numbers, which are more than enough to dominate in the match. Anti-cheat is not a priority right now.
For reference, rage hackers usually have around 70-75% accuracy and 25-35% headshot accuracy, like this guy for example:

@Yoshi may be this information might be helpful to identify more cheaters and may be improve anticheat, since cheaters run rampant now a days.
