Story

What the post asked, what the answer turned out to be, and what the chain says happened. The record below holds the data.

Nothing

A Du Hast video and "Relax. Listen to some nice music. Wait for the idea to come."

Then the author forgot to put the block 43 link in the hash. So the answer field is empty, and the string is BFUB and I have said nothing, a line of the lyrics.

The author claimed to have lost their notes in a Tragic Boating Accident and would not hint. It held 23 and a half days, until the final hint spelled it out: "leave solution field blank". The author then posted the WIF, because it was the link for block 77.

Published answer
As noted in the last hint, solution was to leave the solution field blank. Since there was no link for this, the only thing to find out was the BFUB field. I chose the line in the song lyrics that made me use this video in the first place: and I have said nothing

officialForgot including link in hash. Use only solution and BFUB. Sorry for another mistake.

officialNo space between [solution] and BFUB, but one space between BFUB and [BFUB], and no space after [BFUB], since there is no link in this one.
