Hint 1: Binary is not the only way to encode.

Bonus hint: I know that no one has finished more than 50% of the puzzle, which takes place exclusively on-forum.




SOLUTION

Step 1: The hex colors of the first post represented ASCII characters, resulting in the private key of 1sTPost...
Step 2: My first post was edited. There is a quote with a 0-width image and an AUTHOR md5.



Step 3: Take the md5 hash of 1BbcodE... => 4e01ebd99c8f3610af450d7b8ac4d6cf
Step 4: AUTHOR, as in, user. The member 4e01ebd99c8f3610af450d7b8 has a post:

Make do with the thing᠎᠎s᠎᠎ you ᠎᠎ha᠎᠎ve and don't be some᠎᠎one᠎᠎ who lives life in the past.

Otherwise, perhaps your own locks will be dismantled by what is unseen, but still there.

Step 5: "What is unseen, but still there" refers to the 0-width mongolian vowel separator whitespace characters in the post. They surround the characters for {shaone} => SHA-1.

Step 6: Take the SHA-1 hash of 1BbcodE... => 00e581a7ac7018a61836ca30dc458a200603299d which is the password for the account (your own locks will be dismantled)

Step 7: I sent a message to the account:

The lock is opened by your key, which holds another. But where is the second one?
You're nearly done. Don't get board just yet. Stay hungry for the answer: this will help you decipher everything.

MangepKV2115jq46vEPQfhJgUBbW8ZytkY7McscLgdMQnWu

by your key := SHA-1 hash; second one := placement of the second 1 => 13
don't get board just yet := go to board 13, French local board.
stay hungry for the answer := translate "mange" into English.

Thus we have EatpKV211...

And the beginning of the private key is found via the user's feedback to satoshi: Kigjp...

Done.

Congratulations to LoyceV for being the first to solve the puzzle.
