You Stream a lot of your game time and uploads full rounds to YouTube after watching most of them In my eyes you're legit.
At the start of this video, I can see you have recoil with AN94. At 4:14, when you killed two with M16, has recoil, 6-7 hit markers and you see bullets from behind you so assisted kill.
This video's only 8 mins long so not really useful anyway but you have a lot of streamed videos on twitch some at 4 hours 30 minutes... https://www.youtube.com/channel/UCZzrJ5N54YvA-vmISZ1tPSQ?view_as=subscriber https://www.twitch.tv/skreamevo/videos?filter=all&sort=time
Your initial ban was for 6.35 KPM with M16A3 so if you still have the same the server will automatically ban you again.
