I see. Are you implying whoever has access to Hal's wallet could have produced this signature after his death?

[paulpauper]

exactly. this has nothing to do with proving it is Santoshi, nor is it a hash collision.

All it means is multiple people have Hal's private key and somehow either Martin is one of them, or he was told to post this message.

That's correct.
