This video talks about YouTube’s egregious incompetence (or not caring?) about how easily live stream viewers, views and likes are exploited/fake. And some channels viewbot their streams, day after day, and YT just lets them.
But also, YouTube seems to be massively defrauding their advertisers, presumably for years. If you open a stream in multiple windows and the streamer plays an ad, you get shown a different ad in every window and the streamer gets paid for it. YouTube makes it just that easy to cheat their advertisers. You don’t need to connect the windows with different IP addresses or use browser extensions to make them look like different people or anything special. You don’t have to try hard. YouTube just isn’t really trying to stop their advertisers from fraudulently overpaying.
