Why should I have to create a filter when I never asked for the email in the first place?

If you're emailing me and I didn't ask you to, that's the definition of spam. Gmail has one button that does two functions. Report spam and unsubscribe. There's no way to have Gmail automatically unsubscribe you from a third party list without also reporting spam, so that's the only option I have. (On a side note, Facebook is something I use quite often so I have my settings there tuned to never send me an email. So your Facebook woes are not because of me, at least).

Mosquitoes serve a purpose as well, but I won't apologize for using a fly swatter.

In Gmail - Click on "more" then "filter messages like these" as so - http://i.imgur.com/OdJpKoE.png and set messages from that sender to be automatically deleted.

That neither marks it as spam nor does it unsubscribe me from the list. 99% of the time the message falls into at least one of those categories, and 99% of that, they fall into both spam and something I want to unsubscribe from.

I don't need three or four clicks to get rid of troublesome emails that I never asked for. Gmail has a handy "report spam" that covers 99.99% of every unwanted email I get.
