My son has found blinkx.com, which seems to be like youtube. It has both safe and non-safe image searching, and it is classified as "Entertainment & Music, General, Search". Even though I have set safe search on for my son, he is able to do non-safe searches on that site, e.g. http://www.blinkx.com. For now I have blocked blinkx.com.
