I'm sorry it looks like some creepy list of comments that dox the commenter. Even dang highlighted one of his own comment, where he doxes someone else who commented in the thread. https://news.ycombinator.com/item?id=28940228
You keep using that word.. I do not think it means what you think it means
It's a list of comments where people reveal personal information about themselves.
Purposefully posting things about yourself isn't doxxing, nor is linking to a post of somebody posting personal information about themselves. They publicly posted it, they're fine with it being public.
OK but I still think it's creepy to track a list of what people have said about themselves.
It's a collection of interesting anecdotes. Most people are flattered when others find their anecdotes interesting.
I think you've just described all social media. :)
