There was a lightly visited portal (news) that I got used to and started to bug me to turn off my adblocker (uBlock) if I want to read their materials (I do not call their duplicated things fetched from here and there articles).

I stopped visiting them.

i used to have this for some sites too, but ublock seems to always get ahead eventually

yeah evangelising anything hardly works. people in large are always hesitant to move away from the familiar. i find show and tease works better :)

Ha, you make a good point.

So instead I can show them the same site they're on, but with no ads. Wait for the "how come your view looks different?"
