The bad news is that my friend realized that the account blocking message comes directly from the PDS code logic, so modifying the bsky app to get around the restriction is not an effective way to get around it. The good news is that I found your account status is "Takendown", and only "Deleted" and "Deactivated" in the code logic will cause the account data to be completely deleted from PDS.

So, if you still need your data, just knock on their door every day.
