consider 11-14% a big deal. Maybe some of them are listening....
Well we as root-server operator will have to take the costs of

~From the presentation I refer to which unfortunately is in Swedish but
you can probably read the numbers anyway... :
this is clearly not the case. The rfc1918-queries consistute the bulk
of bad queries ("DUMMA frågor" on page 4 of the presentation). I must
however confess ignorance as to what queries are 'useful'. Presumably
even the rfc1918-queries were deemed useful for someone since they
were sent in the first place.
The 2% figure I think was from an analysis of f.root-servers.net.
i.root-servers.net seems to be seeing more "valid" queries than f. I
guess these figures are different from each server. I think Liman said
that we where seeing 25% garbage in total. I think queries from and
about RFC1918 addresses was around 20% of those. It would be fun to see
what percentage of the Ipv6 related queries that are for site-local
