Re about this compeltely open code internet advertisement blackholing : https://pi-hole.net/
Why do users use adblockers. Many not to come into contact with malvertisers and malvertisements.
Also one of my main reasons to use uBlock origin for instance.
Still the overall number of people that adblock (and third party script-block) is far too low (in my country, the Netherlands, only 17% of Internet users use adblockers), this percentage should only grow and grow.
For the moment I feel quite comfortable with FireHOL IP lists enable in uBlock Origin on Windows.
FireHOL blocklist is regularly maintained: http://iplists.firehol.org/
