Hi Sholland10. I have bunches of questions pulled. Usually the memo from hubpages said it was like Luis stated encouraging a discussion. I have a few that were deemed polls and not questions. We are not suppose to poll in the Answer area. And, I have 2 that were not posted or pulled as soon as posted with no reason. So, I think those just flat out broke the rules of how to post a question.
I am not sure about responding. I presume you mean in the Q & A section and not by contacting the person. The question section has undergone some changes I think. I thought you had the opportunity to respond once to an answer like The Frog Prince said. But, you do have the power to delete responses to your questions.
