I agree. These days I don't report email as spam if it has a (working) unsubscribe link.
You'll get a link to unsubscribe (to just that campaign), or unsubscribe, but somehow get your email back into the victims table.
Me personally I won't give a pass to business with an unsubscribe link, I have extreme disgust that we're in some make-believe pretend world that I asked for this in the first place
