That doesn't really address the question in this thread John (AdTrafficQuality).
The question in this thread is what Google knows about these "crawler(s)" running amok on publishers sites and what they are doing about it. The link/quote in the OP mentions that Google is aware of the problem.
This is Andrew from the Ad Traffic Quality Team at Google. We're aware of a problem with a third-party crawler in the network that is generating invalid activity across a number of different publishers. [productforums.google.com...]
Has Google solved the problem?
