I can't click through if you don't exist

A tale of misconfigured DNS wrecking someone’s campaign.
I got mail this morning from A Large Computer Supplier, asking me to fill in a survey about them. I had some feedback for them, mostly along the lines of “It’s been two decades since I bought anything other than rackmount servers from you, maybe I’m not a good advertising target for $200 consumer laptops?” so I clicked the link.
