HN has anonymous accounts and personally identifiable information can be hidden or removed by the user, which to me has the same effect. HN complains to me that I cannot reset my pwd if I ever forget it because I didn't even share my mail.
People often claim anonymous platforms are doomed to fail but I think social media is the main problem currently.
You can email dang and they'll work with you depending on what privacy stuff you need, but yeah it's a manual process.
People have changed the users on old comments they no longer want associated with themselves and such. There was discussion a while back about it (I haven't taken advantage of this myself).
Only within a certain timeframe. Unlike reddit eventually your comments are no longer deletable or editable by you, and you have to email the webmaster in this case to ask for an old comment to be manually deleted, its not even an automated mechanism.
True. But the associated user might not be identifiable and I think you are free to edit any details here any time. You cannot really do much with raxxorrax or asdff.
