Those codes are from a decade or longer ago. And a secret code that is known to the world is no longer neither a secret nor a code.
Think about it. I know that "code". I want to drive a stock price up. I make a few "911" or "700" purchases. Investors think this is MM's talking to each other. Investors flood the market with buys, driving the price up. I sell at the peak & walk away with everyone else holding the bag.when it drops.
Now, if you really thought this secret code worked, what you needed to do was NOT blare it out all over ihub. In other words, keep the secret code a secret.
