You'd be surprised. I just took a 30 second snapshot on one of my
busy servers, and better than 10.5% of the queries were for invalid
On a related note, does anybody know what app might be responsible
for generation queries for names like hitbox.txt, hitbox.txt,
sextracker.txt, gator.txt, advertising.txt.
.txt is always in the top 5 TLDs queried for me.
