To be fair to him/her, I have tried unsubscribing from various mailing lists before and following that link did absolutely nothing. The link it went to just didn't have any options for unsubscribing. The only way to actually get off the list was to email the group in question and ask them to do it for me.

Although that was a couple of years ago so I'd hope they'd have fixed it by now.
