Story

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

Another four letter word

"Do you know another four letter word?" "No, not that kind" is right there in the format.

It's Hoax again. The author dropped the word TOMI from the hash, and a player claimed it anyway 66 minutes after funding. The author later printed the WIF and still can't explain how the winner got past that.

I somehow managed to drop the "TOMI" part, hashed with the string "Hoax No, not that kind of four letter word. 9iSUoC9".
