Yes, I received a promising reply yesterday. It seems someone tried to access the account, which they mentioned could be due to malware. However, I'm now having trouble with the next step: signing a message with the wallet I used to pay for my Copper membership to prove ownership.

The issue is that it's been a long time since I made that payment, so I don't remember which specific wallet I used. I believe it was an exchange wallet, which I understand is not ideal for this purpose. I'm hopeful we can find a better way for me to verify my ownership soon.

Thank you for all the helpful responses. I will be sure to update everyone once I regain access to my account.
