He left a month, before they pulled their scam operation, what's so hard to understand that he's not involved in their scam?
He is the one that got scammed by them, they ignored the fact that they owe him money. Therefore, we banned them before something more serious happened. And it's not him who banned them, and it's not decision that was just made up in minutes. It's a decision where every staff member had all facts in front of him, and found out that they should be banned.
People were buying hosting with them after he left. Where do you find his involvement in scam? Were they scam while he was with them? No. So? Did he took your money and run away? No, he wasn't even paid for work he did. He was scammed more than anyone else.
