The only way is reporting the file to bitzi and then commenting on it. Just remember just because a movie has subs, it not automatically a bad file. Some people might even prefer it with subs.

Having said that. You just report the file. rate it after the quality of the rip, and then in comments say that it has embedded oriental subs.

Go to http://bitzi.com and download the BitCollider. Install and open it. Then drag the file to it. It then analyses the file and submits the bitprint to the site. You then rate and comment on it. (Think you have to register at the site to comment)
