I identified some hack users who utilize multiple account and CPU for bounty caches. While their main characters clear GR, their multiple accounts clear bounties and give caches to the main character, which are the clear evidence they are using xxx-botting program. I attached the video below (one of them is a broadcaster in Twitch). All of them is from Asia (Korea) server. I included their battletag in my youtube video.
