Re: What about sites that detect ad blockers?
"Or modify their content to look like ads so it "accidentally" gets blocked, forcing people to turn off their ad blocker for that site to see the content?"
Then I don't see the content. Fair dos - they have a right to get paid for their work, but my experience is that most sites abdicate responsibility for what advertisers can do to the web page, browser and PC cos it's easier for them to do that than to take responsibility for their sites. If it's news I'll search elsewhere for it if I'm interested. Otherwise I'll struggle by without it.
