Getting access to an old account

Hello, I used to play on Tallcraft a very long time ago. Way back before Minecraft merged accounts with Microsoft and because of this. I have lost my account (KKPats) and I have no way of retrieving it.

My question to a admin, is if there would be a way that I could get access to my old land claims if that’s even possible. I am completely fine if its not possible. I just spent a lot of time on this server and I think it would be nice to reminisce in my old builds and remember what I put many years into.

Anyways. Thank you - KKPats, ArtThouApe
