Have you ever used your phone to record stuff and put it on youtube?

I have done that before. I was recording my sister as she was freaking out some of the kittens somewhere in our house. I uploaded it and it did went to my account. It has been a long time and its already gone in my account for some reason that I don't know. I wasn't warned or notified that the vid offended anyone or any notice that it had to be deleted...
