You know when you watch a YT vid and after it's over, other video choices appear to the right of the viewer box and several of those on the right will also appear in the viewer box?

What if the other vids were inappropriate choices or their content was so offensive as to make the owner of the channel want to distance herself from them? How could the owner of the channel/maker of the video limit or remove other vid choices that pop up after?
