If this is a true story, I sympathize with you. I've lost crypto to lost keys before.
Now I challenge anyone that is using my account to prove that they own the account.
I had to think very hard about this to make it as fair as possible.
So my request to the hive witnesses is simple initiate a power down on @ranchorelaxo account.
Even if the witnesses were to do something like this, the burden of proof is 100% on you. Even then,
Not your keys not your crypto
still applies to this request.
