Have you tried looking for it in your ad review? Supposedly you can even search for specific ads now.
tried searching for "chrome" "chromebook" "chrome book" "google" and nothing comes up.
that ad review thing is a waste of time i reckon. i've looked through it loads of times and the same ad seems to appear multiple times. you block it once, and when you come back it's still there.
i reckon they must be blocking ads based on the full URL rather than just the domain.
so if you block www.example.com/page.html?id=1 it will just reappear as www.example.com/page.html?id=2, www.example.com/page.html?id=3 and www.example.com/page.html?id=4.
no matter how many times i block an ad in that thing, they just seem to keep coming back. i don't even bother with it anymore.
