No one? Please help. It is very important to me. If anyone knows, it will be wonderful...
I attached a copy of the YouTube Application Control ruleset. I am not sure how old it is, but I don't see anything that would keep it from working on newer versions. It is working in my lab on 220.127.116.11.0.
The rule set pulls in data about the video's title, category, credit (uploader/channel), description, and keywords. There are also sample rules that are applied against that data that you can modify to match what you need.
These rules will not effect searches, but if the result of a search is clicked then it may be blocked.
