The other side of that coin is doubling, tripling, quadrupling down on how innocent I was (knowing full well I wasn't) and having no chance of getting my account unbanned. Even then, backpedalling and admitting to it after vehemently denying it would be an even worse look. A confession is meaningless when it's your only option because you've exhausted all the others. Better to get in front of it and have a slim chance than try to play lawyer and end up with nothing.
No online game, not even major ones like Call of Duty are going to "give you proof" of why you deserved to be banned. It would out their anti-cheat methods and make cheating even easier. It feels more personal of a ban here because at the end of the day, there are no executives behind the decision, just normal people like us- and that's what sends people into the rage spiral when they get caught. How dare this normal everyday person ban me?
