that's very true, because I uploaded a lot of videos and didn't find any of them just after they gave me the link of those video, they are stored somewhere but not seen in dtube or in my channel, and if they take those 25% why to not upvote the most original contant, mine is all original, they even upvote some people that steal video from the web, but not the original content where people spend a long time to do it.
