Huh. My own most recently registered domain promptly got a parking-advertising spam. ("Why let the host collect the money when you can keep it yourself"-- yeah, for the six Ukrainian robots who visit on a typical day.) They must have crawled during the 24 hours or so after the DNS kicked in but before I replaced the host's placeholder page.
the same domain was getting a lot of invitations for romantic opportunities
