This seems to be a list of fake names and addresses. See http://gist.github.com/192658/ef073d2c9109b9da8d439a5976fee7... The list of names is similar to the one you linked to.

Searching for "github dodgit" did the trick. How come i searched for it? All entries contain an email from a throw away address. Since if found the file directly by searching for the first entry I figured the file is part of a project and that it would most probably refer to the throw away mail providers.

Now you've taken all the romance out of it. I was expecting wild conspiracy theories.

Looks very suspiciously like test data:

Exactly 10,000 rows in the dataset

Every name (Firstname, Surname, Streetname) occurs ~50-70 times

Every email address is from a small set (~5) of mail hosts

And the street addresses (all German) don't actually exist - I tried a sample -, street names and cities seem to have been combined randomly.
