Leffen did nothing wrong, Hax's original video calling him fascist or whatever was fucking retarded schizoshit and he would have been unbanned if he wasn't trolled into making more videos about him. As far as I can tell the a-logs fucking with him after the ban are the only ones at fault
I'm not going to say that Leffen was the main cause, but his role wasn't inconsequential. You're correct in saying that Evidence.zip 2 was schizoposting out the ass. TKBreezy and others had the right idea, tell Hax to take the video, have give a sincere retraction and apology (which he did), and maybe ban him for a few months to a year.
Moreover, every time that Hax made a video about his ban appeal, which I think was fucking retarded that one of the conditions of his conditional unban was that he couldn't address it, people would magically show to threaten Leffen over the Internet and now he is scared for his life. And all of this would be laid upon Hax's shoulders even though he would disavowed this and asked people to leave Leffen alone. Leffen would be a weasly little cunt and not explicitly blame Hax, but the way he addressed would let people that this was a cause and effect situation. More than that, since 2023 Leffen has only attended 8 events which at this point would make him semi-retired. He knows for a fact that no one was going to anything to him, but he to be a disingenuous faggot and make it seem like people were going to Shinzo Abe him in the name of Hax.
My thing with Leffen is that he's a cunt, he knows he's a cunt, and everyone knows he's cunt. However, people overlook it because they like what he does. Hax went too far, there's not denying that, but at any point, Leffen could've let it go. Leffen himself was banned for Evidence.Zip and greatly improved his attitude, though he still was cunt (especially to Hungrybox). It would've been easy for Leffen to say in the past 2 years, "Hey, what Hax said about me was really fucked up, but I think he's been punished enough. I personally would be okay with him being unbanned, given that he no longer attacks me. He doesn't have to like me, I don't like him, but I did some fucked up shit in the past and I was forgiven, so I would like to extend that courtesy to someone else." But he didn't, all he ever did was play the victim with "MuH iNtErNeT dEaTh ThReAtS". The best thing Leffen ever did was not say anything after Hax died because it would ring hollow.
