Hello,
so I noticed a player that seemed a bit sketchy with consistently pretty high K/Ds. I watched them for a few days and they seem to be doing exceptionally well in every round. Also for some reason only playing on one server only.
While spectating them while they used a helicopter I noticed that the camera movement is really linear and seemed a bit snappy. Also recorded a couple of clips, here's the latest:
The battlereport of that round: http://battlelog.battlefield.com/bf4/battlereport/show/1/1053714653440458880/1066945208/
And the 24/7 Fair Play page: https://www.247fairplay.com/CheatDetector/IllllIllllllIIII
which also shows suspicious stats.
