My Grandma has DNS level ad blocking enabled. Why? Because her ISP home page (her 20 year strong default as well as login for email/etc) used run ads when a page was left open for a while. She'd unlock her laptop to find full on porn ads running full screen with no way to click away without quitting the browser.

So now she runs ad blockers galore and pihole across all devices. So far no porn ads in her email.

And no I did not ask if any of her browsing behavior would lead to such ads. She's a tiny old blonde Christian lady that...wait also a church donation site gave her porn ads too. Maybe I should avoid checking her history.

So yes, do enforce ad blocking on your network, if able. It will save a few calls and probably embarrassment as well.
