The right to erasure is not absolute, it only applies in certain circumstances. Here's the UK ICO's advice on it: https://ico.org.uk/for-organisations/guide-to-the-general-da...

In the list of "When does the right to erasure apply?", I'm not sure which one you would argue if you wanted to have your HN comments deleted.

1. The data is still necessary for the original purpose

2. HN doesn't rely on consent for this data (I don't think?)

3. I think HN are using legitimate interests, so you could try to object to the processing. I think HN could argue that their legitimate interests override the objection?

4+ Don't apply

So the only one that might work would be point 3. IANAL but it is in HN legitimate interests to keep the comment.

I'm not certain, it seems a bit woolly now I've written it down. It might depend on the seriousness of your objection.

Overall though I think it's important to remember that the right isn't absolute, you can't just have all your data deleted whenever you like. That's not the point of the law.
