Distinguished from spoofing by using technical measures to make an impression appear to be something it is not. Most commonly, this involves creating a shell website such as “diychef.com”, which appears to be a cooking blog, hosting a simple web page on that domain containing nothing but an ad unit, and using an IFRAME to load that web page on an unrelated website (such as piracy site “primewire.ag”). Simple automated identification of the domain of the ad will read “diyched.com”, which is technically the domain the ad is serving on, but is misleading as it is actually loaded into another site.
