Looks like it to me, but support still needs the demo, not a video.
Highlighting suspicious timestamps by noting them down in the email is worth doing too.
flick could be normal but the movement afterward just looks like he got confused, so the follow up which would make such a flick seem legit was not there. this is then pretty blatant aimlock.
The thing was he played like a moron. Rushing with LG.
Then I saw him vs another player and it looked wierd. He had so wierd aim Ive never seen it before.
But im not an expert in hacking and I dont know how the new cheats works. But look at his stats.
Hes rockets are like a newbie, he hits LG/Rail better then TOX but still loses to players like me.
