FURIA coach used the exploit in March 2019
The author of the investigation about the coach exploit Michal Slowinski published a video on his Twitter, which proves fraud on the part of FURIA coach Nicholas "guerri" Nogueira. The Brazilian was found to have used the bug in March 2019, when his team met with Complexity on ECS Season 7 for North America.
guerri secretly collected information about the opponent's actions throughout the card, which did not help FURIA win Mirage. Despite this, the Brazilians with a score of 2:1 closed the series and reached the final of the tournament.
No, I do not enjoy doing this to any of the coaches or teams. And no, I am not aiming BR scene specifically.— Michal Slowinski (@michau9_) September 2, 2020
It happened, I found it and I reported it - it literally is my job.
