This isn't that. A danger people need to be aware of is one thing. Something that has nothing to do with us is very different. We all have sins, and none of us want those acts to be discussed here. This guy just had the misfortune to have his sins broadcasted on TikTok and picked up by gossip rags.
I agree with this part of your post and would give half a like if I could.
As far as toeles, no one who is thinking of doing this is under any illusion that they won't be shamed and shunned if they are caught. They either think they won't get caught or that the risk is worth it. This conversation isn't preventing a single sin, just providing entertainment.
This part, on the other hand, I couldn’t disagree with more.
I’ve seen this sentiment expressed around here before, people saying public shaming, prison, and other consequences don’t help prevent further crimes, but nothing could be further from the truth. Every time people witness someone publicly shamed for their actions they become much less likely to sin in that fashion. The Torah uses this tool and all penal systems do as well. Public shaming is a massive deterrent.
Before every action we take we make a little cost-benefit analysis. When the seeming costs outweigh the seeming benefits we don’t perform the action. It isn’t perfect but to suggest this conversation won’t impact anyone reading this is simply incorrect. As you mentioned, all of us sin sometimes in some ways and realizing that we may be the next fellow talked about on DDF will certainly prevent some of us from pushing the envelope too far.
Still, I tend to agree with
@YitzyS that even though it is likely not LH we should think about his unwitting victim (his son). It’s not quite the same as a molester, rapist, or fraudster where we have an overriding duty to his past and future victims to publicize and condemn his misdeeds.
