Story

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

A stray link

"AOI Second." The answer is AOH, and the field is I after H.

The author typed a stray link into the hash, right where the link placeholder sat. It held 19 days. The claim came 36 minutes after the author published the answer and the typo.

The fallout: the second run would start with a 77 mBTC block, as a penalty for this one.

Published answer
Solution to this was AOH, with TOMI field I after H. So I should have hashed with "AOH TOMI I after H 64bSJfY" but actually hashed with "AOH TOMI I after H *link* 64bSJfY".
