Over 1 million players were banned from PUBG in January alone and it is still going on. The community manager of PUBG, Andro Dars announced a week ago that the company is working hard to test its new anti-cheat measures on the test server for the game with no server downtime.
The main goal is to get rid of the cheaters who use programs to change the game files, so, it provides an enjoyable environment for all the fair players. These programs such as ReShade are used to alter the graphics or aid in gameplay in some way. Any program or app that is used to transform the game files or behaves like a cheat will be blocked as well even if it doesn't give any unfair advantages.
