Use the autoblogs as a means (like a blogfarm) simply for passing link-juice to a target site/page. You can use adsense, cpm...etc. on THAT site/page.
You can still get something from the autoblogs themselves though. On each autoblog, add an opt-in for a newsletter, tips and tricks...whatever, just something relevant to the niche. You can make money from the subscribers with aff links in the report and/or pitch them something periodically via email until they unsubscribe.
