>I too have watched Numberphile. Rest assured, there's little to no risk of their extremely popular videos being bad. No, I wasn't talking about Numberphile. I was actually talking about videos from Institute for Advanced Study: https://www.youtube.com/user/videosfromIAS/videos https://www.youtube.com/user/videosfromIAS/videos Last month, every one of those videos that had a young female professor in the thumbnail had the "men of culture we meet again" spam and other rude comments. All the comments have been recently deleted and disabled. >Hacker News, a website providing nothing but informational content with no visible downvote ratings? The HN (net) downvotes are visible because the posts are greyed out. For tech topics (not politics), I don't scroll to the bottom to read a bunch of greyed out comments. Downvotes lowering their visibility are saving reading time on HN. Same idea as Youtube dislikes.
