Why doesn't Yahoo! Answers have a mutual adding system?

This is an excellent question and I seem to be also a victim of this kind of slandering which unfortunately the Yahoo team chose to act on. The really annoying aspect is that after I provided them with a perfectly accurate explanation of why my answer should be allowed they just leave me hanging in the air with no response. I think we should press for a mutual adding system as a matter of priority. I agree also that such issues are not evident on other sites.
