I'd assume cybojanek is talking about majordomo-like mailing lists, the sort used by lots of open source projects, which typically require an email sent to a specific address with "unsubscribe" in the subject line and so on and so forth.

Curiously, having to email <mailinglist>[e-mail] to unsubscribe from a mailling list is, to me, preferable to having to login to a website in order to unsubscribe from the same mailing list.

I think it's because I'm beginning to resent the idea of every website and its dog requiring that I have a user account before I'm allowed to even browse the content.

You're not alone. I much prefer majordomo to any other web-based mailing list system. I just chalked it up to a greybeard quirk; HN at large seems to be the opposite.
