Not many; if at all, will come out and say exactly how they find their end users as it's their tried and true method to their secret of success. It takes work to find the perfect end user and that's why domaining can be a full time job. There are millions out there, just have to learn the correct approach and be a good salesperson.
Most responses you'll receive (if any) are: if your domain is good, an end user will find you. Some don't like the waiting game and take a proactive approach, just don't be a domain name spammer.
P.S. don't spam your posts with links to your affiliate site, it's a one way ticket off of the DNF platform.
