This sounds a bit like whitewashing. He's a bona fide scammer and a sociopath. inputs.io happened before my time but I was around when he exit-scammed with hashie. He set up the scheme with a purchased hero account, managed to get into some sort of partnership with a reputable (at the time; later exit-scammed too LOL) hardware vendor, and then didn't just run away with the funds - he trolled everyone on the way out. And again blamed a "hack".

His attempt to refund his victims was also just a form of trolling really. He refunded a few, nobody knows if they were real or just his sockpuppets. The he just stopped issuing refunds earlier than promised. I know at least two victims who didn't even get a response from him.
