Exactly, "report spam" already serves well as "block" as well as "unsubscribe".

I try to unsub first, because if I opted in they don't deserve to be marked as spam. But if your unsub method doesn't work. You are 100% going to get on every spam list I can put you on.

The spam button in gmail was the auto-unsubscribe button too.
