There abouts, email is free, for a certain class, so adding a lot
of names to the left of the @ is very old school but also
a lot of the scrappers end up with all those weird usernames
that appear in email headers as part of references in mailing
The ratio does vary depending on age and usage a domain
has had so I'm serious when I say it could vary as much
as +10 -50%.
