I don't think there's a thread for this yet? If there is, sorry.
As of about 102 minutes ago, the Quick Look: Rabbids Invasion: The Interactive TV Show (01/10/15) has caused the GB Infinite stream to end presumably due to YouTube's weird policies/scrapers about using content from a TV show as the QL does contain footage from whatever Rabbids show was on TV.
This is (at least according to chat) not the first time this has happened with this video, and other videos have apparently caused similar problems.
I'm not sure what the best idea is to deal with this (take it out of rotation so it can't be voted on?) but probably having a list of the main offenders that cause the stream to die will help out @wcarle immensely.
[Edit as I was there: during the Rabbids thing, the video cut off at least three times while watching, presumably during the bits where the TV content stuff was visible. I am assuming, but do not know for sure, that they were probably content warnings. Eventually after the third-ish cut-off the video feed went completely offline.]
