One-click unsubscribe

Currently, unsubscribing from box emails requires the following steps:
(1) Click unsubscribe
(2) enter email
(3) copy 6-digit code from a new email to browser
(4) select 'opt-out' instead of 'opt-in'
(5) select confirm my preferences

All of which are a failure point to unsubscribing for a user who never signed up for emails to begin with. Other services only require step (1), and it seems box's choice to add impediments is intentional. I would like to see box display an attitude of helpfulness and customer respect, as well as comply with the US Federal law restricting such behavior:

§ 316.5 Prohibition on charging a fee or imposing other requirements on recipients who wish to opt out.

Neither a sender nor any person acting on behalf of a sender may require that any recipient pay any fee, provide any information other than the recipient’s electronic mail address and opt-out preferences, or take any other steps except sending a reply electronic mail message or visiting a single Internet Web page, in order to:

(a) Use a return electronic mail address or other Internet-based mechanism, required by 15 U.S.C. 7704(a)(3), to submit a request not to receive future commercial electronic mail messages from a sender; or

(b) Have such a request honored as required by 15 U.S.C. 7704(a)(3)(B) and (a)(4).
