I've noticed the trend as well. My CPM has dropped to about 1/4 of what it was (only slightly higher than AdSense) in the past 10 days. I think banning a lot of domains last night will help a bit, but it is still a major hit for me.
I am aware that each advertisers experiences will be different. Do not judge based only on my experiences.
