Story

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

Think

June 24, 2019. The post opens with a thought about advertising. Pay money, make people look at a message. The quizchain does the same with prize money, the author wrote. Block 46 could have been a political ad, and this one is "similar in purpose".

The question is Think. The answer is two words, the first capitalized. Same for the TOMI field. Digits 2c1, e and f3.

Think different

An ad with one word, Think? A fruity company comes to mind. The answer is Think different. The TOMI field is Apple slogan.

u/puzzleponky posted the whole string right after the claim confirmed at 14:00:37 UTC, an hour after the post. The author never edited the solution in. That comment is the only place it's written down. u/Quantris was late. The very first thing they thought of was the answer.

Published answer
This was not that hard given the word "Think" and the topic "advertising campaign" as there is a particular fruity company that has used this.
