How is posting videos from YouTube taking that persons credit? Unless you upload that video to your own channel and take credit for it. The act of simple posting it on a site does no harm. The video is still linked to YouTube and you can go to the uploaders channel. By posting the video(s) on websites it makes that video and uploader more popular since more people are able to see it.

Notice the quotation marks young one.

Hmm..sharing a video is taking credit for it. Your an idiot. I just pasted the title you idiot.
