Yes, that was my question.
I rejected your edit because I intended the title to evoke curiosity.
That is the explanation I put in when I rejected the edit - that it would make the question worse. I went into detail.
And no, I don't think that titles of puzzles should have to hold descriptive value. Ambiguity is often part of the puzzle.
A descriptive title would have been "Cryptogram of plaintext MAGICSIBLINGS using a simplified Pollux cipher". But then there's no puzzle to solve so what's the point?
Your proposed title was something like "Clue for ... [other puzzle]", which, while it's true, doesn't describe the content of the cryptogram puzzle at all - it doesn't mention the type of the puzzle, or the plaintext or the ciphertext or the cipher. Which are all there is to describe.
If my questions doesn't have enough 'seriousness' for you then I suggest you don't visit them. In that respect, a title without much 'seriousness' could be useful in that it could alert you to a question which you're likely to dislike.
