He once reported Jim Hogshire's opium growing to Seattle police after Hogshire threatened him with a rifle, and he reported a fellow to the postal service for sending him a mail bomb, so many people will chime in with something about him being a snitch or a fed when he's mentioned. He also criticized some SWERFs back in the early 80s that were working with Republicans to crack down on porn and sex work, so he's often accused of being a misogynist. He was part of various left wing groups back in the day that did the collapsing and infighting that so many groups tend to do, and often gets accused of any number of things because of that - Chaz Bufe has suggested that he tried to burn down someone's house, or instructed one of his "followers" to burn down someone's house, when the zine they worked on together in the 80s fell apart. IIRC the proof of that was that the owner of the house smelled gasoline outside once. Black was the guy who came up with anti-work, so he's often accused of being a lazy drunken layabout by the non-anarchist left.
When it comes to most anarchist subs, I personally think the real reason for the negative reactions is two fold. He's very critical of Bookchin and Chomsky, so anyone whose anarchism is centered on them tends to not like him. He's pretty abrasive in his writing, so many people think he's an asshole, probably rightfully. But, it's a lot easier to just say "Hey this guy's a snitch!" than critically engage with his work, or say you disagree with him cause he seems mean.
In fairness, the one Sub Genius, John Hagen-Brenner, had sent him a mail bomb. Not exactly an unreasonable time to report someone. Weirdly enough, it's the more reasonable incident to accuse Black of being a narc. The other one incident involved Black reporting a poppy farmer/author's operation to IIRC Seattle PD after the farmer threatened him with a rifle.
It’s not illegal you can buy it on Amazon. Idk if I still have the PDF or not though. I think I lost it. Still fairly cheap for digital or physical copy on Amazon
