Hi, I created an account seven years ago (or so my dashboard says) and I had completely forgotten about it. I was quite surprised to suddenly receive a newsletter in November, and I'm uninterested in continuing to play. So I was wondering if anyone knew how to delete my account? I don't mean freeze it, I mean permanently delete it.

you can't delete your account, only self-freeze.

Just stop playing. People who usually want to stop donate everything then self freeze and call it good
