Is CriticalBliss an American company? If you really want to ruin the guy's life/grift, leverage the Lanham Act and take the trademark of CriticalBliss from him. You can do a version of this even if CriticalBliss is an international company.
1. 3 Consecutive years of discontinued use of the brand = presumptive Abandonment of the brand
2. Start new business called CriticalBliss, whose primary form of revenue is generated from Consumer Protection Watchdog activities that report fraudulent companies; Optionally, make CriticalBliss into a YouTube LLC that monetizes seeking out high-profile failures for viral videos.
3. Laugh as the original owner of CriticalBliss has to drag his ass into court to defend his business practices in order to keep the trademark.
