that totally depends on how much targetted traffic you bring to them and how fast you do it... having a huge network of automated blogs in fine and dandy...but they won't make money without anyone going to them...
Unless the content makes sense I don't think people spend much time on auto generated blogs I know I don't simply because it looks like bunch of gibberish, also alot of auto blogs steal content which is morally wrong IMHO
people sit on those autoblogs are those who buy such packages for a fortune from so called gurus and they dont have a choice other than sitting on it....about how much it makes.....LOL....good websites with content and heavy page impressions can get few dollars a week if the niche is not high paying....you need to put up effort and take pain in the process to make money....nothing is easy and free
