Rephrasing his question, Can our question or answers be used as evidence in court to incriminate or help???

Raichasays and coranth1 answered that question perfectly. Nothing in here is evidence of anything. There is a huge disclaimer that you can read by clicking at the bottom of the page (go ahead and look, I'll wait) that will tell you that (not in so many words, but in a nutshell.) Also, if you wanted to use any individual's answer, you would have to call that person into court to testify, so they could authenticate the answer (state that it is actually their answer), and then testify about its truth, and where they got the information contained in it. I thoroughly doubt any competent judge would let you do that.
