Yep, you need all of those crappy 10 character domains, 50% of them at least in the .com gTLD, to support most of the spam crap in the 1 Billion "active" website sea of fools.

from: Netcraft | How many active sites are there?
The front page is taken from each hostname on an IP address and then compared with the front page of other hostnames on the same IP address. Only sites with distinct content will be counted, such that unique content is counted once no matter how many domains and hostnames point at the site.
Where an IP address serves a large number of websites, it is infeasible to sample all sites on the IP address, both from a logistical viewpoint and from an acceptability viewpoint. We therefore apply a sampling technique and extrapolate the results across all sites hosted on that IP.
Accordingly, Netcraft do not visit all sites on an IP but instead take a random sample of sites. For an IP address with N sites, Netcraft retrieves:
625 * N / (N + 624)
sites.
This means that for IPs with a small number of sites (<100), almost all the sites are visited; and for IPs with huge numbers of sites (>100000), around 625 are visited. Keeping the number of requests to be under 700 even in the most pathological case ensures that the survey robots are not banned from sites, and that the results remain respectable and accurate.

.com may be the king of spam. Maybe, 1,000 names made it the other 134K+ .com domains haven't done shit. Sometimes, you have to look at the big picture. The 1,000 that "made it" didn't make it because of the domain string -- they made it because they were worthy, marketed and branded.
I wonder how many .coms are not developed and held by domaineer speculators? 10%? IDK
