YouTube将打击网络恐怖主义

                                                                                  

      YouTube will "fight online terror". It will find and delete dangerous videos. YouTube will delete videos on how to make fire-bombs.
      There are still many problems. It is a big job to look at so many videos. Over one hour of video is uploaded on YouTube every second. One hundred years of video is uploaded every 10 days. Another problem is that many of the videos are not illegal. Terrorists could use a BBC news video in the wrong way. A final problem is how to delete videos that do not break YouTube's guidelines. YouTube will use software to find videos that help terrorists.
