Thank you again everyone for your comments. Some of them have been helpful.
Tomorrow I will take down the HN front page. Your accounts will remain in case you still want to check things out. You can also delete your accounts yourself, or ask to have them deleted.
If you want, you will still be able to create a new account from the default main page https://katesapp.org. You will need to ask for an access code, but I'm happy to provide one.
Edit: Sorry, the option to delete your account has not been uploaded to the server yet. However, email me at the address in my HN account, or contact me through the app, and I'm still happy to delete your account for you if you want. Again, thank you everyone.
