For context (especially since all of Jim's posts are, guessing, gone from YouTube for the time being), Jim Browning is an impressive 'white hat hacker' (not sure he'd use that term himself) who spies on, stymies, and exposes intricate scam operations. In addition to reversing connections to those who attempt to remote-desktop scam him, his escapades include collaborating with local authorities, accessing CCTV networks of offices where scams are run, and intercepting scams that are currently being carried out on unwitting, scared citizens.
He mentions he was recording the attempt. I assume the scam was made possible because he was going along with it to some extent and accidentally went too far.
Wow, this is shocking that the scammers out-scammed Jim Browning, a well-known YouTuber fighting cyber-scams. I hope the channel is restored as soon as possible! I wonder what recourses are available when you delete a YouTube channel yourself...
