alt Hacker NewsAn example I remember is when Virgin Media replaced any DNS queries returning NXDOMAIN with their own "search page" plastered with ads.

Ah, yes, I forgot the NXDOMAIN hijacking.
I was thinking about interfering with existing sites.
AT&T still does this, if you're using their (intentionally terrible) standard gateway device the default DNS will return a "search page" instead of NXDOMAIN which predictably has all sorts of negative impacts on non-browser devices but the wastes of oxygen responsible for this don't care as long as they see that delicious ad revenue.
