Instead of discussing how to find the key, the talk is about how to steal it. Those claiming it is ethical have no sense of manners, and those saying the RC test is part of the game should note that the creator deliberately leaked the public key to test how fast it could be cracked. but he never said to steal from someone else after finding it.
lol.... The supposed creator made only a bitcointalk forum post about the challenge, he never said anything about rules on how to compete in the challenge or how to get the coins to your wallet, he also never mentioned anything about leaking puzzles with multiples of 5's public keys so to test how fast it can be cracked.
Step into reality for a moment and you will realize that your feelings or anyone else's feelings does not matter about ethics in this competition, since no rules were stated for the challenge anything is acceptable.
