The irony being this site doesn't offer a decline all option.
Not bad.
(which is also why framing GDPR discussions around cookies misses the point - the point is to determine the user's consent to being tracked regardless of technical ability, whether cookies, IP address, fingerprinting, or even some magic crystal ball)
That is also illegal under the GDPR; you cannot track me without my explicit opt-in consent, whither by 'cookies' or other means.
I continue to be astounded how little grasp some HN readers (a technical news site!) have of the GDPR.
