Lauda was a forum account. Lauda committed "suicide" by making it impossible for him to access this forum. Lauda no longer exists.
Lauda also revoked and/or declared compromised all keys associated with her identity. That is more significant; and I believe that she fully understood why.
My only
PGP-key has been compromised and revoked. All previous Bitcoin signed messages are invalid. As of this point there is no way to confirm ownership of Lauda.
That being said, the real person could be posting under a different account name.
Although such a negative cannot be proved, I am morally certain that Lauda is really gone. I don’t know why there is a common urge to speculate about alts, as if people
cannot leave this forum. What is this, Hell? “Abandon all hope, ye who enter here.”
