it is 99,99% accurate. It takes a TON of work away from the developers. It would be so extremly time consuming to handle every ban personally. If someone was wrongfully banned he has the option to apply for an unban for that special case. Of course being wrongfully banned is bad, but it's absolutely the easiest and best way for gaming companies to handle things.
You are expecting things that can't be expected. I'm sure that even if a company has unlimited time and money to create an automated ban system there is no way for them to reach a 0% false ban rate at such a high player count.
And btw. the bans mentioned in the article were not even automated.
That's why it's a problem. They ARE being handled personally, and people's purchases are being invalidated because of rules that are vague at best and made up on the spot at worst.
