Player d3nZ#tired has played over 200 games with his friend noxis.

noxis uses special software or a script based on AHK, which hputs a lot of strain on the internet. In the attached video, you can see how at some point his ping disappears. This allows him to easily check the enemy's position. After disabling the script, the player teleports back and starts pre-fire, aiming at the enemy.

As far as I know, similar abuse was used a long time ago in CS:S.

For a general understanding, I recommend watching the video in its entirety.

What is your opinion?

A second video is being prepared, which will contain much more proof.
