Hey OP, you have said that the previous account had some good reputation, That means you are a very known person on how to recover a hacked account. Now I am very curious to know why you did not try yet to recover your account?
Now you should move this thread in Meta and with all information, for example, the previous account link, previously staked bitcoin address if you have, etc. then it will be very helpful for you if you really want to recover your account. Good luck
