Hi there, thank you for being patient with your appeal. If you look at the below report you will see why you were initially banned. You were banned for multi-hack because a demo was supplied which showed you using drowning/teleport exploit most commonly found within cheat clients. You also had a constant 60 ping, yet went from smooth gameplay to a constant stutter / lag which seems purposeful and deliberate. All of these actions can be witnessed in the demo file located in the below report.
These actions look to be very suspicious and of a cheating nature, unless you can prove to me those were not cheats and I can replicate those actions on my own client without using modifications your appeal will be denied. If you can show me how to replicate those functions in my own client and prove they are not 3rd party cheating software please comment below with further information.
I will give you until the 25/04/2018 to comment with more information, otherwise your appeal will be denied. Cheers!
