Same situation here, got banned a month ago already. Submitted many tickets of appeal to the ToS but they were all denied.
Just before the ban occured I had a couple of bugged games where I was kicked out of the lobby and lost my KP or I finished under the map and I was stuck there so I had to force quit the game.
And then BAM the code snake appeared and i was permanently banned for good, marked has a cheater.
Just incredible, I'm now starting to lose the patience and the will to keep on fighting against this unjust and unfair treatment.
I will probably quit for good with Apex and give up on this matter at all, too much frustration and thoughts on something that isn't really worth wasting time.
It's a shame, I love this game and I've been playing since Season 0.
