I suppose that's hypothetically possible but it's hard to imagine it'd be 
worth the effort.  There are a lot of domains for sale (even though few 
have the tag) and most are basically worthless.

It is also my impression that turning NXDOMAIN into web ads has largely 
gone away.  A lot of the ISPs I see don't even bother to provide a DNS 
cache and point the customers at 1.1.1.1 or 8.8.8.8.

R's,
