If he's not back already with this one rebranded or he isn't already running another one under the radar.
Going after the domain name or trying to find the people that had their identity stolen is a waste of time, as by the time you have the paperwork to deal with it the "team" behind this scam, they would be at the 20th or 50th project already.
This is a Whac-A-Mole game with 3000 holes running 24/7 and you have one hammer while they are starting to get AKs.
Unfortunately, we're catching only the stupid ones, I'm not going to give them ideas on this topic on how to do it but if they would not be that cheap and spend 50-100$ on their "project" all the investigations will not be able to find anything bad with it.
Tag them, call their scam in their topic, open a scam accusation so if you google their name you stumble upon this and on to the next one
