I'd be interested to hear the current state of play from the pros, if any are on here.
I have a hosts file with lots of the dodgy ad servers redirected but some sites detect this approach as an ad blocker.
I suppose the Raspberry Pi Pi-hole option would encounter same, if the site it actively checking if the ad was loaded ok somehow rather than checking if an ad blocker plug in is active.
One day something (cough, crypto micropayments per page view, cough) will come along so the sites don't need to rely on ad money and they'll get less in your face about blocking them. One day.
