I've used the exact same content in small paysite rings & on AVS & without a doubt, AVS retains like mad. I have members for over a year on sites I've never updated.
I didn't use AC but the AVS concept works best when you weed out all the crap & just allow quality sites with original content.
How many webmasters that were weeded out were slapping up sites with sponsor content or rock bottom stuff that's been seen a thousand times before? AC members will probably stay even longer now...
