Must be another company mooching off of AnandTech.....that's what happened last time. I don't know how it works, but it's possible apparently. I HIGHLY doubt this is AnandTech related, as Anand himself has stated that he will NEVER use pop-up ads, and that he has made this VERY clear with the advertising company that he hired.
EDIT - speeling
EDIT2 - wowa....it's locked? Mods......Dare I humbly ask why this is locked?
EDIT3....weird, it's not happening now. Weird.
