If you had somehow posted a Yahoo Answers question on your Facebook, would it show up in your Activity Log?

Also, where would the question be posted? It would be obvious to you if you had posted a question because you would be able to see it, right?

If you sign in to yahoo using facebook, you will see a note which mentions that yahoo will not post or share any question or answer to your facebook account (this note was shown to me to). So there are no chances that yahoo will post any question or answer to facebook.
