CSCs whole deal is securing domain names for huge brands, they probably have people whose job involves thinking of derogatory domains like that so they can grab them pre-emptively. The people behind the .sucks TLD turned that into an incredible grift, they charge an exorbitant amount (about $300 a year) because they know every big brand will buy brand.sucks no matter what.
I worked for a company where MarkMonitor proactively registered domains for us which were likely typos of our brand (e.g. example.com -> examlpe.com, exmaple.com, etc), and would hunt down registrations of new domains which appeared likely to be phishing sites. They didn't catch everything, but they were pretty good.
