Has anyone spotted these ads on The Verge and Polygon?:

They've been popping up over the last couple of days for me. According to Cory Williams over on the Polygon Meta forum they aren't Vox Media ads (Polygon Design Feedback). I'm in Australia if that helps and I used Safari with all extensions disabled when I took the screen capture...

Anyway to get rid of the crappy ads is appreciated :)
