Speculation on Spam - Tactical perspective

[Nic Name]

In my experience the worst spam attractors are Hotmail, with its pre-selected opt in check box to share your email address freely and Network Solutions Whois registry. All domain registrations should use specific email addresses that can serve as spam-baskets.

That said, Hotmail is a nice spam basket especially with the new filters that moves everything to Junk Folder with maximum privacy settings.

In the early years, when NetSol had the monopoly on domain registrations, they wouldn't accept a Hotmail address for the Domain Name Administrator. Even today, using Hotmail in the Whois could be a hassle, if you lost your Hotmail address in their new purging program.
