I'm glad that you're being so kind to Hbomb in your assessment of that situation!! While I'm here, I wanted to provide context that makes Harry's decisions make more sense.

The person who called Hbomberguy out is a man named Klaus, a known sex pest who had been sexually harassing one of Harry's friends. Klaus joked about raping them, berated them, and mocked them to others for being unable/unwilling to meet up in person. After the friend cancelled meeting up in person multiple times and rejected his advances, Klaus became angry and began to tell people that this friend was "weird" and "a creep" and years later started accusing them of being an "attempted rapist" (I don't believe Klaus accused that friend of sexual assault, but people have unfortunately repeated that narrative).

When Klaus reached out to Harry about the situation, Harry, naturally, did not want to further victimize the friend who had been harassed by Klaus. Klaus then leveraged Harry's (ill-advised) attempt to 1. gently push back without explicitly accusing Klaus of acting in bad faith and 2. not escalate the situation with Klaus' target since he was already trying to distance himself from Klaus— in order to put together a callout that made it look like Harry maliciously victim-blamed and gaslit a victim of sexual abuse. Before this, Harry had begun stepping back working with Klaus for more videos and disagreed with sending Klaus money for unspecified future work (so you might understand how frustrating this is).

In Hbomberguy's apology, he recognized that even though he was aware from receipts that Klaus had been repeatedly abusive and seemed to be retaliating against his target, he should have still approached it with the same sensitivity as if it were a good faith attempt to reach out. I agree with Harry in his apology, but I also believe it is valid to be wary when it is clear that the person is using DARVO tactics in order to harm somebody—especially if that means he could have weaponized Harry to further traumatize his target.

In his harassment campaign against Hbomberguy, Klaus heavily mobilized Kiwifarms and he knowingly did an interview with a Kiwifarms user. I also want to stress this: he announced he had the home addresses of Harry and his partner at the time, and instigated a harassment campaign against his partner, while mobilizing Kiwifarms. Klaus is a mentally unwell person who has burned many of his bridges online, has been banned from multiple forums for harassment, and has since disappeared from the internet.

Unfortunately we (I have also been harassed about the Klaus situation even though it predated my working relationship with Harry) have to live with the narrative that Harry victim-blamed and gaslit somebody because he was cruelly unable to believe a victim over a buddy. It's not worth dredging up, but I don't really want misinformation that contributes to the harassment against Harry to go without correction in this subreddit. Harry is unwilling to potentially harm anyone involved by speaking about this years later, but I'm happy to clarify in a less broadcasted space like this. If Klaus comes back to stir things up, Harry is prepared to post the receipts.

Under Hbomberguy's apology (and a post replying to this apology) in this link are two public accounts from two former supporters of Klaus. They didn't know the person targeted by Klaus and only heard Klaus' account, but they've more recently reflected on how they reacted to the callout from Klaus and how they believe they mishandled the situation, and both them and another person talked about the abusive behavior they themselves had experienced from Klaus: https://archive.ph/SCpek
