Oracle is a red herring - look what Google DID
The sting used the IRA's own tax details to confirm that the ad buyer was who it said it was. Google accepted these.
The sting used images and text already known to have originated with the IRA operation. Again, no problem for Google. No filters were tripped.
In fact, Google said "Great stuff guys" and even chose a picture to make the ads more wonderful.
Whenever Google PR says, "Look over there, Oracle!" you know they've really fscked up.
