HN has a lot of successful low quality submissions. I'm sure one about the curiosity of this domain existing, redirecting to this site, and having its whois hide the owner, could be a successful low quality submission. But the HN guidelines make it clear that having a lot of mildly entertaining low-quality submissions isn't a goal. It's just a part of being a fairly open community.
