Rutineli, if nobody - whether the addressee or anyone else - ever sees and understands your disclaimer, I'm not sure in what sense you have managed to "negate responsibility". Saying, in the immortal Scottish words, "It wisnae me!" really only makes sense if someone hears you, surely.
Your idea, it seems to me, is just like that of the little boy who tells his mum a fib but 'knows' his conscience and immortal soul are stain-free because he has his fingers crossed behind his back! He and God know the truth.
I just wonder what the law would, indeed, make of your stance if the matter ever did result in a court case. But good luck to you, whatever.
