I feel like the people cracking these are keeping the keys for themselves 'cause the creator might send more funds to those wallets one day, as this already happened before.
Didn't #125 have like 1.25 BTC the day it was opened, and later on it got +11 BTC sent to it?
That would be a pretty good reason to keep these keys close to your chest.

Because 125 had not been deciphered at that time, as you will see, 120 did not receive anything else.
