This is a similar example, albeit a little less extreme.
When a person follows the unsubscribe link from MoneySupermarket’s email newsletter, they are presented with this page. The focus of the page is clearly the signup form for another newsletter, presumably the same one that I am trying to unsubscribe from. The actual unsubscribe field is presented at the bottom of the page, in a location which would probably not initially be visible on most people’s browser screens. This could also be seen as an example of the Roach Motel Dark Pattern.
