I know lots of people who are masters at hiking, backpacking and wilderness survival, and none of them need to spam other blogs to get recognition; they get recognition from being awesome.
So, my thought is that the people who spam their domains are only masters of being opportunistic jerks. If you've achieved mastery of anything, I would expect you would promote your web sites in a way that's also awesome.
Most of the "names" people use are non-descript sounding like Sarah Parton, Jane Smith, Julie Smith, James Terrier and Tessa Wildfire. I can look in my email history and see dozens of these.
