On the right side of the YT window are typical "suggestions" for further viewing based on searches. They've now added streams that are supposedly "live" with links like: "LIVE :BREAKING NEWS NASA announces! RED ALERT!!! (Planet X To Pass Planet Earth June 2018)"
Other than posting "fake news", the so called live suggestions are oftentimes, rebroadcast of previous live streaming events. So in other words, NOT LIVE!
