I've lost lots of money with Youtube ads sending me children trying to learn their abc's. Lot's and lots of children searching for cartoons landing on my channel against my geo/language/age/interest filters. A few hours on the phone with their Indian tech support got me only false promises of call backs and refunds. I'm unable to reach intelligent/useful person at google adwords tech support. Which is terrible, because I think that's where most of their revenue comes from?
