I got this bug on desktop, running chrome, with no VPN.
This was, as most things like this are, just a pure dumb fuck-up by some guy putting things on prod without properly testing and staging. No need to put on any more tin foil hats than we already have, the incompetence is plenty reason enough to point and laugh.
On the flipside of this, I've been kicked from games because I know how to prefire, and a lot of players see that and just assume you're wallhacking. Nobody pays attention to the 70% of the time that you prefire at air, but when you guess right and instakill someone holding an angle, it's easier to say "cheater" than "i've been holding this same angle for the past 5 rounds, perhaps I've become predictable"
