I made some brief analysis and it seems to be more complicated for the
following reasons:

a) Not all advertising is served with a dedicated DNS hostname

or example facebook serve it on http://facebook.com domain.

b) It's not easy to catch all URL and to modify content without breaking
everything

Implementing a transparent proxy server for exit traffic only, without
breaking tor traffic would require such feature we discussed some time
ago:
https://lists.torproject.org/pipermail/tor-talk/2011-March/thread.html#19765

However i am now making a 1 week collection of dns query and url requests.
After would check that lists against adzap and other ad filtering
software that include list of hostname, urls and pattern.

That way we can use an advertising blocking software to check how many
ad traffic was here.

So we will have some numbers, purely for private amusement, to be used
for calculation into a spreadsheet to be shared.

I do very often proposal that could lead to 'bad exit designations' :P
