There is more solid proof that they belong to the same person than what you are referring to.
Please, feel free to exhibit the aforementioned proof.
Lauda did a pretty good job of figuring out who these purchased accounts are
here.....on his 1st guess

You can review the
sent trust of Operatr, and you will see the connection is admitted via trust ratings.
I would also point out that none of these purchased accounts have a negative rating from lauda, even after seeing they are all purchased. Most (all?) of the accounts have neutral ratings from others indicating the accounts have been sold with references/proof.
