I'm perfectly fine for the ban (although it was kind of unfair), but I was wondering how I could demonstrate "ongoing pattern of good sportsmanship" so I could start earning "free Loot chests or other positive player rewards".
Also, how will I know when I have been good enough?
You'll need to not receive any bans for a period of time, time varies, around a few months usually
Continue playing and try not to get reported, if you fall under the raider you eventually return to their good graces. just expect to wait months, not days.
Its entirely random. It took me about 5 months to become eligible, showing that I was "reformed", only to be permabanned a day later.
say gj and try to be positive when you have chat restrictions. It's what I did before I was randomly banned.
Sounds like it's time to make a new account.
