I found this interesting; The Jewish Internet Defense Force has a list of videos that they deem offensive and they ask people to flag the videos for deletion and most of the videos have been deleted. So who knows what types of unseen videos that were on the web before they were scrubbed off the net. I liked the internet back in the 90s better.
These are videos which are clearly antisemitic, promoting violence, or breaking other YouTube rules. More will be added. A more comprehensive list can be found at thejidf.org
