Thanks very much for the list. I searched a lot of networks to find mellowads, which has been best for me, but will try some of the ones you provide in this post.
If you have a faucet with good traffic and at least 100k rank in alexa, I would suggest to try coinad as it is 6-8x higher than mellowads. I'm earning 5million to 8million satoshi a day with coinad.
