IIRC up until very recently the screening process was "they report that they're good boys."

The screening process has been more involved in that since around the late 2000's. I wouldn't call 20 years "very recently," especially in the context of the history of the web.

circa 2007 I was looking over a college textbook on computer networking that I saw at a family member's house. It still said "While networks are inherently unreliable, it's not a stretch to imagine a future where one can stream video on-demand over a WAN like the Internet"

circa 2007, Youtube had been around for two years already.
