Why would you pay them everything upfront? And why would you expect upwork to ban them for a project that didn't happen on their platform? How was upwork ripped off by this guy? Wouldn't you be as responsible for ripping them off by moving the project off the platform? You haven't been banned but are demanding someone else is? You have a judgement against the developer so money should be recoverable but you seen unable to collect so you are trying to hurt the person instead? Stop, you are wasting more time / money on a mistake. You originally had a $6,000 idea. Keep focused on getting that built. This is a distraction and your success depends on moving on.
