Hey Jon. I have some bad news. You entered your Nostr private key into your Nostr address field. A Nostr address is like an email address. It's not your private key. You've accidentally given the world access to your profile. Sadly the client that your using doesn't do any sort of field validation to stop this from accidentally happening. What can you do? You have to create a brand new set of keys and start over. I'm sorry this happened.
