okay, to not spam that users wall.
Imo the embedding of the video on this page isn't copying the video. cause the file is not hosted here. it's embedded, not copied. if you start doing that with videos, you have to question every single picture. I get, that we got to ask before changing pages and code, cause it can mess stuff up, but you would need loads of people, checking every single video and picture.
It would be easier to lock the option, to edit title and description of the video. I take this video as example. I didn't edit anything, so every other user could see where it comes from. Why bother checking every video, instead of locking the editing part?
