If a service puts me on a subscription list without asking me, and then at the unsubscription page throws a questionnaire at me as to why I am unsubscribing, I take that as dishonest behavior. Obviously I am unsubscribing because I never subscribed in the first place! Depending on how completely unrelated the subscription is to whatever I signed up for (say I signed up for online image hosting, and they start sending me emails about their fantastic paid backup service) then I mark it as spam even if the unsubscribe button is easy and single-click.
