My understanding is that the GDPR “right to be forgotten” applies to personal data. Are publicly available comments considered personal data?
If they can help to deanonymize you, they must contain something personal. Writing pattern are pretty personal, certain spelling errors too, or the choose of words.
From ico.org.uk: “ It is important to note that opinions and inferences are also personal data, maybe special category data, if they directly or indirectly relate to that individual”
From gdpr-info.eu: “ Subjective information such as opinions, judgements or estimates can be personal data.”
So yes. HN is in violation of the GDPR. I had already filed a complaint about this policy at my local GDPR authority.
Well, the username attached to them would surely be.
