On my first visual question (which isn't lateral-thinking), I have placed the important letters on certain locations, and then proceeded to fill in the blanks with nothing relevant to those letters.
Instead of filling complete random numbers, I placed here and there some words to form a red herring that could be used as a more silly but still believable answer to the puzzle.
I have thought of disclosing the red herring as an answer after placing the checkmark on the valid answer, but is it okay to do that ?
More generally : is it okay to disclose some red herrings as answers on our own questions ?
