Why was my question deleted??????

I had a question on yahoo answers about an ad that I once saw but I forgot what it was called. No-one answered, and when I checked up on it, it was deleted. I did NOT violate any guidelines and the ad was a nintendo one, which definatley did NOT contain anything unsuitable. Why was it deleted? Are the y!answer staff a whole pile of monkeyes that randomly delete things and choose best questions or wat? It would be funny if they were tho. It would also be funny if this question wasn't deleted.
