If no one can figure out your riddle, that doesn't mean you're smart, or it's a good riddle.  Literally anybody can make a riddle that can't be solved.  

(The Poem isn't unsolvable by any means: anyone who plays cryptanalysis games would immediately see the solution.  It's just that anyone without much cryptography knowledge has no idea where to even begin.)

That people got frustrated and gave up doesn't show you made an elaborate riddle, it shows you made a riddle no one really cared about solving.  If it were in the middle of a story with characters, more people might have tried to figure it out, or if there were side puzzles that could be solved in order to get some sort of hints or clues. 

hi hank! you can turn off dueling in your profile if you don't want people to challenge you.
