I don't want anything, I just showed the OP that anybody can do that, exactly as you described it!

The OP did similar, did choose the values to fit the math, hashless signature. This is why I was asking for a signature from the public key he posted or a plain text "z" he could show, not only the hash of it

I don't waste time with useless things - so not solving anything regarding this "challenge" either, but I feel the whole game goes for finding a related key, which from the currently crafted r,s,z pairs won't happen anyway!
