unfortunately videos on facebook now no longer need you to point or click on it. they automatically play as the video gets in your screen when scrolling to read any posts that your friends have posted. once the video is at a point where its not touching the bottom or top of your screen it plays.

anyone can report offensive videos to facebook for their removal by going to the top of their screen and clicking on the help option or by clicking on the video itself and selecting the report\spam option if the video has that option enabled.
