Some sites pretty much do this already (Popular Mechanics, for one). I get a nice popup when I arrive at their site that says I need to turn off my adblock to continue.

I actually don't even use adblock -- I use pihole, which means I'd have to add who-knows-what domains to my DNS whitelist (not just popularmechanics.com, because if it wasn't already permitted I wouldn't have even got to the page with the popup). So back button it is.
