Story

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

"42"

Everyone knew the answer since block 24. "But do you guess the slight twist on it?"

The twist is the quotation marks: "42" BFUB quotation marks emF. The author wrote that Reddit removed the post for a while, and the copy that survives sits on the author's profile. It held three days. Weeks later a player posted the string and the WIF "for posterity".
