How do I delete all my site data?

I think the best way to "vanish" would be to have your user renamed and then deleted.
You can then make a new user with a different name, just make sure to build a few storages in the first 3 matches.

Deleting forum posts only makes sense if there is private information in them.

Exactly what "Right to be forgotten" means depends on Jurisdiction.
However, I would believe it doesn't really apply to anything posted on these forums.

when I type your name in google, it finds a lot of information about you, it's going to be difficult to delete all that, you seem to be really well known

there's a lot of information about your life in gotham city, your family, your friends

You can't. Your activity here is a public contribution to the Zero-K community. Threads lose their context without your posts, other peoples' games and ladder rating don't make sense without your ingame actions. This stance tends to work as people rarely post private information here, and what little we have on a technical level (IP addresses) is retained for moderation purposes.

We offer a form of deletion where your account becomes "Redacted", which makes the forum a bit harder to read for others but at least avoids turning threads into Swiss cheese. If you have posted private images or doxxed yourself in a way that you now regret, you could contact the moderators directly for some targeted deletions.
