Nobody. It should be understood that we simply provides a mechanism (or Usenet web interface) to post via NNTP to Usenet newsgroups. We do not control posts or discussions made in these newsgroups in any way whatsoever! Once you post a message here it will be forever existent in cyberspace and indexed on hundreds of servers including the likes of Google. You will not be able to change it or delete it. So think extremely carefully before you hit the submit button to post a message.
