First off - a bit of clarification. Appeals are not a place for you to explain or plead your case. It is a fresh set of eyes to look over the data used to do the investigation and merit the sanction. That’s it. Blizzard uses the data created behind the scenes and nothing else.
And you may have lucked out before their processes changed, depending on when your last run in was. I won’t argue facts, I’m sorry. Instead I will leave you with proof that the appeals process works. Sometimes it does take a lot of back and forth, and often times longer than anyone would really like - but it does work.
