> It's not my duty to click an unsubscribe button if I didn't subscribe in the first place. Then it's also not your duty to click the spam button?? Joking aside, that's not the kind of email I am talking about. Spam is spam and should be flagged as spam. If you get benign email that complies with all the anti-spam legislation but you just don't want it, then use unsubscribe. Using the spam button for things that are not spam muddles the data labeling and increases spam rates because the email service operators can't use it to tell what is actually spam and what is a frustrated (or perhaps simply ignorant) user.
