Where did you get the url from? Have you found other similar urls?

I am unable to find the origin of this link. However, it looks like it is used to play the videos tagged as Active Events in this youtube channel: https://www.youtube.com/user/BreakthroughBC/videos?flow=grid&view=46&tag_id=UCrCa0A58nblJV_Mum6gXyUQ.3.active-event . This is the first url of this kind I have found.
