Cpm model in general is not a bad thing.
Lets say on average per 100.000 impressions you get 10.000 clicks and 1 sale for 15$. Lets say it cost you 10$ to achieve that. It does not matter if ad network charged you:
a) 10$ for 100.000 impressions
b) 10$ for 10.000 clicks
c) 10$ PPS
In this scenario a) is not worse than b) or c) just because a) is CPM.
It matters when they serve a) in dishonest ways you described.
So problem is not CPM model itself, problem - shady brokers. And most of them are shady to some degree.
I am almost certain that person who invented CPM model did not invent it for cheating purposes. Networks did that.

I can agree with this. Initially i feel CPM was created to get rid of Lazy webmasters and thier shitty banners. If you have a shitty but brandable banner you could take site owners for months gaining visual branding without people clicking. or People who let their banners go staleeating up your precious inventory.
CPM made webmasters work for traffic/branding.
The problem on the Flip Side with Click bots etc it makes a CPC market without good checks in place a rip.
CPM/CPC hurts when you get Broker ontop of broker and sometimes even on top of broker Sellign People the Same Surfer for 2x or More Premium because they need to bid up to get the first impression. In Some cases you could be fighting your self if you buy from multiple networks.
On top of that you need to look at Circle Jerk networks redirecting traffic to themselves. Doesn't help you at all but helps them as they are Selling you a "unique view" on that site even though they have been shifted 2-5 times through their network.
If you can Avoid or minimize those CPM can really be effective for you.
on a Buyer end Defiantley you need alot of Different banners. Remember there are alot of bookmarkers so your banners can go stale fast.
Sorry if this rambled a bit but i think i covered some good points.
