That's a pretty weird objection. Even if there was a button at the bottom of your profile page that you could push to delete your account, there's nothing stopping that button from notifying some real person behind HN who could peruse your posting history before deletion.

> Even less privacy in my opinion.

What "privacy" are you talking about? You've posted these comments to a public website, where any user can view your entire comment history.

> But beyond that, it won't delete your messages. I guess they just own my words forever now.

I haven't read HN's terms of use or privacy policy (I suspect you haven't either? Ironic, considering the tone of your post), but presumably, as a condition of signing up in the first place, you've elected to allow that practice.

As a fellow HN user, I think it would be really bad for the community if random bits of old discussions just disappeared, making it difficult or impossible to understand the conversation that was going on at the time. I certainly think there should be exceptions; say you accidentally (or regretfully) posted some personal information that should be deleted... I believe in that case the HN mods would do you a solid and delete it. And I know that in some (all?) cases of account deletion, they'll make up a new username to attribute your posts to, which would dilute any association the posts have with you (assuming you used a name that you've used in other places).

Regardless, there's nothing stopping someone from scraping HN (or using the HN API) to mirror the content of discussions elsewhere. And they might not be in a jurisdiction where you can expect to get your data deleted if you really want to.

To me, these privacy/deletion laws are most useful to force a corporation to delete any data it has on you that it holds privately, and could use to identify you or monetize you or whatever. Once user-generated content comes into play, it feels like a different beast to me.
