Hi Gothweb, I am sure "free avs's" are appealing at first but if you are thinking in the long run you are losing lots of money with them and concerning your main goal "to drive filtered high quality avs traffic" you must go with bigger and paid avs systems...
Cyberage is what i use, they have high "new listing" traffic, "featured listing" which will send you stable amounts of traffic, and great payouts with platinum or even prefferred program.
I know it looks like a spam post, but hey i love them. Whats more? "8cents everytime someone clicks signup button even he doesnt buy" , "7cents everytime a member with password visits your site" , and regarding your previous message they have solid free hosting for your own domains...
Good luck !
