this was already discussed a million times (use search). Satoshi's account here is locked and besides posting on that account does NOT prove anything as bitcointalk database is not the safest thing in the world compared to a digital signature from a bitcoin private key!
The digital signature is the biggest proof of ownership it is the one thing that we all been waiting for, for several times so many impostors are coming without this proof, but still proud to boast that they are the real Nakamoto, we are tired of people coming without knowing how to open the official wallet of Satoshi Nakamoto, hopefully in the future, the real Satoshi will come if he is still alive, so everything will be settled once and for all.
