It'll also randomly kick you from games for having various programs installed or running. Programs such as VMware. You have to disable all VMware services or PUBG will kick you randomly for using "unauthorized applications." God forbid you have any VMs running, that might amount to a ban (seriously).
Worse still is that when you take your complaints to their social media, or in anyway speak ill of it, you get hordes of fanboys saying that you shouldn't install anything other than games on your PC or you're a dirty cheater. "Oh you want to do things _other_ than gaming on your PC? You should buy another PC then."
Don't even get me started about trying to run games in a virtual machine w/ GPU passthrough. The communities will tear you a new one telling you to do things "normally" and by attempting to use anything other than the "normal" setup makes you a cheater. Just google anything like "steam vac kvm" or "battleye kvm" and you'll get hordes of people claiming they heard some guy say virtualization is the future of game cheating therefore VMs are cheating tools and should be banned.
Seriously, if I could get a refund for every game that uses BattlEye, I would try.
