Can spammers really use the WHOIS database to extract information? YES
Do they need detailed hostnames? NO
On Linux/Unix/Mac systems, a whois command line utility is readily available, brute force lookups are very easy to script, and even if the WHOIS utility is not available, it is very (for most) easy to write a script that connects directly to the WHOIS servers to fetch the information.
