Yes, I’m talking this from my business experience. I’m selling software. It was cracked and thief is easily selling it with adwords now. He has top ad’s position in Google (despite several dmca notices and not only from me) and Google doesn’t care about it as long as they get good money from thief.
Google must share responsibility with the scammers for false advertising and the customers and sellers should have a way to make Google pay for promoting scam. The ads cost should be proportional to the possible damage.
