I don't think they do unless you have a very high alexa and good content / traffic. I'm not completely sure though. It's best to email one of their support members.
Hi, Mostly you need have at least 3K - 5K traffic per day to get blogspot approved, So i would recommend you buy a domain and get alexa below 100K then you are ready to get accepted. Regards -logon2future
Cpxinteractive only accepts some websites and blogs. I think the interface of websites is very important for them. They don't care to the traffic a lot. I know some one with about 50,000 daily traffic for his website with a good Alexa ranking but when he registered on Cpxinteractive, they didn't approved him. So i think they will not accept blogs.
