rakaCN is Raka Han from China. He is copying my YouTube videos with my explicit permission. The reason that I gave my permission is that I have many Chinese fans, who cannot watch YouTube through the Great Firewall.
Raka is TP Forum member. I have sent him an email with the request to respond to your post.
Thanks. When I first brought up the subject with him a while ago he apologised and said he'd make them private. As far as I can tell though they are still public and he has uploaded many more. I have since then sent private messages both here and on YouKu but to no avail.
Although you need a little help (thanks to that person who helped me) to set it up you can use YouKu yourself.
