Played with and against him on multiple occasions, and followed him around during a game in which he went 120/1 in a server where nearly all other players were not even close to half his kills, which raised an alarm. then I followed him around whenever I could (he was a tank player who was taking out targets consistently from afar)  i could visibly see that the turret of his tank was tracking non tagged targets which were obstructed and/or across the map. other players in this lobby, teammates and opposite team, also agreed upon the very high possibility of aim software.

This became evident later on where he was able to achieve very high accuracy in gunfights in high object density maps such as pearl market, consistantly hitting triple kills on single mag on non grouped targets.

If you observe the player behavior you would notice that there is a pattern:

he gets reported a few times, he changes his username (sometimes once a month) and continues the trend.
