conjecture: the dominant *legitimate* use of whois today has not been mentioned.
nerd logic: o spam scrapers are not counted, as they are not legitimate in my book o other uses of domain and addres whois lookup are not automated o the one big automated use is router config builds using the routing registries
o Registries, registrars, etc. for domain names
o RIRs for IP allocations, ASNs, etc.
o RRs for routing policy data
