Is this the process for every account that is blocked or it is just for satochi's only? Just asking to know.
It depends. Satoshi's case is unique, the account was just voluntarily locked by admin. If your account is locked or stolen. You have to prove that you are the owner of the account by signing a message from a staked address and sending a message to the accounts recoveries time.
If it banned or permanently banned, you can try appealing the banned but chances are so low that it will be unbanned
