Have to agree - we've seen a marked increase in fraudulent and suspect traffic coming from Yahoo and upon further investigation it appears Yahoo has picked up some the partner sites that Google tossed a while back (Zanga.com & Sedo.com).

In terms of Yahoo's new fraud report - why can't they report to us the referrer that delivered the "bad" clicks? Would make sense so we could block the site. Many outside vendors now offer ways to seriously deter and detect click fraud - why can't Yahoo?

In addition, why does Yahoo not allow advertisers to opt out of the partner network for search partners in the same fashion that Google does?

Most on this board know the answer to these rhetorical questions. In an effort to boost quarterly earnings Yahoo is alienating many of the customers they've worked so hard to retain.

A serious effort by Yahoo to cleanse its search network and offer proper tools to understand and combat click fraud would pay dividends more quickly than Yahoo realizes.
