You mean the guy that showed up on Joe Rogans podcast? Yea that guy is a fraud, there's a whole video about him by a youtuber called Chill Goblin, you should check it out: Anarcho-capitalism and the TRUTH about Michael Malice | Chill Goblin
Often times I found myself agreeing with him at first, but then realising... this dude doesn't know jack. He responded to Joe Rogans question that was "All anarchists believe in abolishing the police. What do you do to protect yourself?" and he responded with something along the lines of "You hire private security." He even says things like "there should be an open market for security guards."
Any anarchist that tells you there should be a "open" market for security is a giant red flag. Michael Malice is trying to steal the label "anarchist" just like Rothbard did with the word "libertarian". These are people that steal leftist labels and actively discredit REAL anarchist thought by spreading their shitty ideas and labeling it so. Do not buy into this shit and call it out if you ever encounter it IRL.
