This is a feature in some well known client . It will give you a notification something like this " X player had been detected for Killaura Hitting Accurate : 99.8%CPS : 13 - 20 Turn speed : 180Possible of hacking : (Very High) 89 % "
Or , a GUI like Jigsaw client which show you the information of players in real time .
This is very useful as users can easily tuned its config to be not lost in the game .
Would be kinda cool
Would be a nice feature to have, +1
So it is a cheatdetection in a cheatclient? lol
