You posted your message because you said you wanted the discussion, and to see the flaws in your argument. But when people are answering you, you seem to be working hard to ignore them ;)

I've taken the sticky note down. It had the word "contrite"

There were plenty of exploits you could have done, without having local access to my machine. Just one example- If you view my profile, you can determine the company I work for. Use linked/etc to message someone there, and offer to split my generous reward with them, if they tell you the word.

Just because no one took me up on my offer doesn't mean my sticky-note was secure.

Yes, of course it was a silly "contest", but that's the point - Contests like this don't prove anything at all about how strong or weak your solution is.
