FWIW, the posts "Fatloss computer program", "HP Desktop for sale", and
"Watch NFL Games Online" are all coming from the same spammer posting, if
I read the path correctly, from zeus.nntpserver.com which resolves to
188.8.131.52 which is:
OrgName: Co-Location.com Inc.
Address: Wholesale Internet Division
Address: 333 S. Beverly Drive
Address: Suite 105
City: Beverly Hills
He's posted to every newsgroup I looked at.
I emailed them at firstname.lastname@example.org and requested they shut him down.
He also gave a contact address in one spam of email@example.com. It's a
waste of time contacting Yahoo, and I suspect the email address is just
for collecting email addresses, but if anyone would like to tell him off,
be my guest.
