my story: when my kids were in age around 5 yo, obviously they were watching YT cartoons, but this will not be story about ElsaGate, this knows everyone.
Some algorithm decided it is good to show during cartoons vasectomy ad. This is weird enough, but somehow I can understand this failed reasoning (kids -> tired parents -> no more kids -> vasectomy).
But this ad consisted only from one slide presenting intersection of penis and nothing more. For long seconds my kids were staring at it before I reacted and turned it off.
I also reported this to my country's authorities and I got some answer they gave Google some fine for this.
