They could also do RDNS lookups and then see what rwhois says about the domain.

They could purchase sales records from online retailers. Hey guys,
give us the IP address, city, state and zip code for each sale; we'll
pay you a nickle each. Then correlate that with BGP announcements that
show the range of impacted addresses.

They could convince folks to install web browser plugins which give
the users rewards in exchange for ceding personal information. Or buy
data from a company which does.
