Then what would prevent people whose videos were banned from suing Facebook because Facebook didn't get their intent correctly? And similarly, people appearing in videos that aren't banned could sue because Facebook didn't see the evil intent. Such lawsuits can be numerous and costly enough to kill the entire concept of hosting user uploaded videos. How to avoid this? Maybe it's better to drop the intent thing and just ban any videos that look real but aren't? Even if it means banning some parodies such as this https://youtu.be/cQ54GDm1eL0 https://youtu.be/cQ54GDm1eL0 Even then we'll need to figure out how do it at scale, since a human reviewer will often not know if it's real. I don't think we can limit the ban to videos where you can see people's faces; you can create quite bad misinformation by showing a military boat of some country sinking a civilian ship etc.
