Story

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

Six words

June 28, 2019. The question is two words, Six words. No TOMI field this time. The digits come with a typo, "MP5 hash", and a player asks if that's a hint. It isn't. Honest mistake, says the author.

Someone tried shat shot shit pat pot pit. "No words of dubious moral standing in my blocks..." Fair enough.

Bat, twice

The trick is block 5. Same idea, five words then: bat bot bit bet but. Every vowel between a b and a t. Now it's block 52, so the first word goes in twice: bat bat bot bit bet but.

Why bat? Because it's two words, the one from Batman and the baseball one. The author calls that a homonym, and that's the excuse for six.

The funding and the claim confirmed in the same block, at 14:42:25 UTC, an hour and 44 minutes after the post. u/kimi_tousan explained it right after. u/BrainForceOne liked the groundwork, not the twist. Checking a doubled word by hand? Painful.
