If someone comes to read the comments before he/she actually completes the challenge, that means he is really looking for an easy solution. Most password(s) can't be remembered from fast reading, the reader must read it carefully with the full intention of remembering (or copying) it. It can't be read accidentally. No spoiling here.

And the second reason, this challenge is really not a challenge at all. It's very easy. The creator(s) need to make it harder.
