If a user wants to delete the comment user should be allowed to delete the comment or account. Period! Reasons like community interest are not strong or proper imho. Also there’s no information about whether HN logs user IPs or any other info. Or info about how many IPs are logged. Whether they log all the IPs or last K IPs. For how long those IPs are stored.
