Note to self: Don't forget to use domain filters when buying Yahoo PPC traffic, and keep an eye on traffic sources in case new 'partners' are added.
From a Dutch campaign targeting the Netherlands, this were the numbers today after not looking for a while. Dutch is not spoken in any of the other countries except Belgium. I am sure they could filter the fraud if they wanted to :(

Yahoo is none-excistant here so we never really ventured into their PPC - luckily :)
I've had the same experience. Shed loads of fraud. We now don't run any Yahoo PPC. We sent them a comprehensive report and never even got a reply.
Is Y-PPC Europe eventually switching to adCenter too? I noticed in the final few months of Ask's PPC the conversions went to shit.
So far Y PPC is Y PPC and not MS.. yet. Dont know if they plan to switch in the near future.
I thought that all Yahoo PPC was now served up by Adcenter. You could choose Yahoo/Bing or both.
You have to watch their "sources" of traffic very closely. The only saving grace is with correct optimisation you can do OK because the traffic is cheap, and let's face it, it's not Google, albeit some of the Adcenter editorial rules have a distinct Google feel to them.
I would use the various tagging parameters they make available to ensure you are getting as much information as possible about every click and prune ruthlessly.
