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 song

June 20, 2019. In the first run, block 44 used a famous rock song. So does this one. The question is a YouTube link to the Rolling Stones' (I Can't Get No) Satisfaction. No TOMI field. One digit block, fd8.

Good solution

What do you put in place of satisfaction? The author picked good solution. Two words, no TOMI.

The format said [solution]. with a dot. The hash has none. A player asked the author afterwards to stop writing dots that aren't there. Reasonable.

The claim confirmed at 16:06:55 UTC, three hours after the post. The winner never commented, so maybe a script did it. u/LiaVl tried (I Can't Get No) Solution. u/JDScreesh couldn't get no solution. The author's reply: that's close.

Published answer
Solution was to find something to substitute for "satisfaction". I thought "good solution" was a nice fit.
