I might need to try this honestly. I got game banned and CF banned/tracked over a year or two ago from cheating. I took a year break from playing the game and decided to try playing legitimately again.
What I do, is contact the admins on Discord for the server I want to play and just be honest. So far, I've been accepted into Rearmed, Perception, and a smaller server called KillerZ. Ground Zero requires 3 years minimum from your bans (per one admin I spoke to).
This is getting quite frustrating getting denied, though. What is sad, is that it is the community preventing people like myself from playing again, not even DayZ because I can play official servers on my same IP. I made a dumb decision to cheat and now am permanently disabled from playing community servers until I go through all the steps OP has stated, even a year or two later.
There should seriously be an appeal process within the community or with CF directly for people like myself who will never cheat on this game again. At least a one-time "Get out of jail free" card. I'm not technically savvy enough to do any crazy computer changes nor am I financially in a position to continue buying accounts to see if what I did worked.
Since my ban, I've gotten a new computer. In theory, all that is left I need to do is get a new router and new Steam account with legitimate hours? Or what is left that I'd need to do in my case?
