Ok I tested this feature today - there was a belly fat ad on one of my sites, but it didn't show up in the Ad Review Center. So I saved the image, uploaded it, and sure enough it found four ads using that image that I could block.
If it really keeps em off, this is a major improvement. I hate it when I can't find ads I wanna block in the Ad Review Center.
