How about an opt in botnet extension for your browser that focuses it's energy on sites with this sort of dark pattern behaviour. i.e. You install the extension, when you come across a site like this you vote it for getting punishment, once the site gets enough vote the botnet occasionally focusses it's energy on the site in question when the participants browser is otherwise sitting idle. The punishment could potentially be anything (follow subscribe links, consuming traffic in the background, a simple DoS), but ideally something that reduces the offending servers ability to do what it's supposed to.
