YouTube has announced plan "to fight online terror". One of things YouTube says it will do is to find dangerous videos and delete them. This includes videos on how to make fire-bombs and other deadly devices. Google, which owns YouTube, announced four things it would do to tackle problem of dangerous videos. Kent Walker, Google's senior vice president, called these things: "Four steps we're taking today to fight online terror." first step is to ask users to identify or flag videos that might help terrorists. second step is to remove videos. third step is to focus on videos that could make people become terrorists. Finally, step four is to show "anti-terrorism" adverts.
There are many problems with making four steps work. Perhaps biggest problem is that it is huge task to monitor so many videos on YouTube. Over one hour of video is uploaded to YouTube each second. advertising company AdWeek said one hundred years' of video is uploaded every 10 days. Another problem is that many of videos Google wants to target are not illegal. Mr Walker said even BBC news video could be used by terrorists in wrong way. Walker said Google would use software that will learn what content breaks its guidelines. further problem is how to delete videos that do not break YouTube's guidelines but still have content that could turn people towards terrorism.
