I seem to recall this - anybody remember anything like this about Yellowbook?
I don't want to tar these guys unnecessarily any more than they deserve.
I have a recollection of running into YellowBook as a hidden display advertiser - this was back when I was working in log file analysis... (so it was a while ago)
I dimly recall they were a large source of high cost, low converting traffic that was commonly syndicated out to even more useless advertisers who were obscured unless you were paying very close attention.
I seem to recall also learning first-time about GA filters back then that would enable you to see detail about otherwise obscure referral sources.
