My country also set down some laws which those advertisement network ignores. They broke the deal for which those law represent, and they get to live in the wild west for which they chosen.

Give me a advertisement network which takes legal liability for what they advertise and follows local law, and we could start talking about what implicit deal exist when I visit a website. This mean no recording (data protection laws), no malware (anti-hacking laws), fair representation of the product, clear pricing, no alcohol, tobacco or advertisement towards minors, clear indication that its an advertisement, and the other rules that exist in advertisement laws here in Sweden. Tax laws involved are also always involved If there is a deal where service is provided in exchange for goods.
