The problem with display advertising is that too much of the industry is focused on clicks. Anti-fraud companies can come up with ways to try to mitigate click fraud but it won't do much of anything as they can, and will be, gamed by black hats - there's too much money at stake.
I deal with it every day and the best method is to educate the client by explaining why a click is a poor indicator of performance. Work with the client to come up with measurable goals to track click-through/view-through conversions on these goals and ultimately try to measure impact on ROI. It's really not THAT difficult for most campaigns.
The most difficult part is that the client becomes aware of all those wasted dollars on previous campaigns that they thought were high performance because of a high CTR.
