message signing does work and does prove it for legacy addresses '1' prefix (p2pk/p2pkh)

Bulista is not the creator. If he were to call the moon the "sun," it does not mean that it is so. The moon continues to be the moon and the sun continues to be the sun. He can call things as he wants but it doesn't change the facts. As long as the creator of a puzzle cannot prove that
HE is the creator, everything
other say remains only simple speculation which is based on no facts but on pure fantasy.
2 years later, in April 2017, the creator of the puzzle posted a message:
still the same, you don't know the creator. You just
think it is the creator. That's a
huge difference.
I am the creator.
You seriously believe a newly registered forum user (who has no other post except this one, means he only registered a new user name to make his post) that he is the creator of the puzzle, just because he writes it down like that? And on top of that has chosen the nickname "saatoshi_rising", which obviously abuses the fact of the fake that Satoshi could be related. Another user then asked him to confirm his identity by signing a message. This ensures that he really is who he says he is.
That's very nice to hear, but please prove yourself by signing a message with the last address (256) from the transaction, which hasn't been cracked yet.
But he never did that. That the money
July 2017 was deducted from the higher address and transferred to the lower addresses we see, yes. Despite this is not proof that the user "saatoshi_rising" did this and whether the person is Satoshi or just a Wannabe-Satoshi. Fact is at that time: the private keys of this puzzle are known and available to the owner. Nothing more is proven, that's all. No one knows who is behind the puzzle because he never proved it and made it known.
Whoever made those Patoshi outputs (Satoshi's early mined coins) wanted that people figure out there is a pattern[...]
Can you prove that it is? If not, then this is only an imagination, wish, thought, hope, ... or something else illusory of you.
First, I want to make it categorically clear that a puzzle without a clear and definite direction or clues to solving it is not a puzzle.
Correct.
Secondly, for the clues to be truly clear and definite, the private key to the address that holds the coins should belong to the user who started the puzzle game.
Absolutely correct.
...you can not create a clue from a private key you don't own, else the clue will be fake.
True!
And yes, I agree that every user creating a puzzle to sign a message from the address that is staked in the puzzle, to really prove they own the address and coins in it, this will stand as a guarantee or assurance to the participants of the puzzle, that they are not wasting their time on a puzzle that is fake.
Correct. But let's extend your sentence with "... or which exploits the purpose of a puzzle to maliciously attack an address or address space to which you (= puzzle creator) do not have the private keys and thus are not the true owner, but which you negligently pretend to be.
The following is a freely imagined story.
Alice is an employee of the company BigBob Ltd. and manages the finance department. However, after many years of service, disagreements arose and the management decided to terminate Alice, under the pretext XYZ. Alice was bullied and her life was made difficult until her notice period arrived and she left the company. Alice could not prove otherwise, she knows it was unfair but the verdict was in, the termination was effective and she will have to leave the company in less than 6 months. She knows from her last active project that the company BigBob Ltd. had settled a special contract with a future startup company for a high amount of Bitcoin. For various obfuscation reasons, BigBob Ltd. and its future startup company had decided to split the payment based on a certain pattern. The high amount of XXXXXXX $ was thereby transferred to 255 individual payments split to different Bitcoin addresses, which show a linear progression and thus a clear pattern. The reasons for this do not matter any further, this only concerns BigBob Ltd. and its future startup company. Alice, however, knows the individual addresses and also can access the password-protected private keys to the addresses used in that particular transaction but only on a dedicated computer within the company. Alice is enraged and spiteful because she was treated so badly by her former employer BigBob Ltd. She is vengeful and registers on various forums on the Internet, stating that the known 32BTC transaction is a "puzzle" and everyone is encouraged to try cracking those addresses. She never explicitly mentions that the finder can keep the coins. In the last weeks of her employment, Alice decides according some forum talks to make a transfer. She programs a logic bomb on one of the related computers in the company to transfer the balance of addresses 161-256 to certain other addresses below 160 exactly 7 days after she is fired. The puzzle was opened long before. By announcing the transfer of amounts from the high address ranges to the lower ones, it reinforces her credibility in the Internet forum community. In reality, however, she is not the owner of the addresses and the private keys. She is happy to read in the future how the prize money will be taken from the respective addresses of strangers around the world and enjoys the feeling because her former employer and its subcontractor will suffer a loss. In fact what happens is: some people stealing money from BigBob Ltd. and think they're just taking the puzzle bonus. While on the other end BigBob Ltd. recognizing someone's stealing money from their addresses.
