Glad I subbed to your steemit profile yesterday. In my opinion they didn't like the Ken O'Keefe clip you showed, but they probably had you on the radar for longer. Your 9/11 videos had too much views. On youtube you can talk about "libtards" all day long, but there are certain issues they don't want you talk about.
Jeff C from fakenewsreport aka New World Agenda made a video, where he talked about how they are deleting articles about false flags and hoaxes from mainstream media news sites and videos about real conspiracies from youtube. And then Jeff said how people should download important content as much as they can while it is still online. And then youtube deleted his video. There you go.
