One of the reasons why it is advised that you determine ahead of time, whether or not you really want to share your videos with the rest of the world is because once you do it may be too late. YouTube allows video submitters to pull their videos from the site, should they change their mind about having a particular video posted online. While this is nice and the removal happens right away, it may already be too late. A large number of internet users are able to copy or save videos that they find online, including YouTube videos. Should your video fall into the wrong hands, it may never really disappear, as you may find it posted on other area of the internet.http://ping.fm/Bayk2
