Sure but you need thousands of legitimate-seeming pageviews to get that $50 back, and the networks - even or especially the bottom tier ones - are likely to be hotter on click fraud than scraped content.

You would have to get ~16,000 pageviews to make $50. (assuming $3.00 CPM -- which would be low for adsense, but not for these second tier networks).

And 16,000 page views without unique content and links might happen, but most likely not within a year or five.

If you're lucky, you trigger something in Google's black box and they rank your site better than others at the same level, but you'll still only do long tail, and even on long tail, you'll compete with the original source of the article, which has a billion links pointing to its domain. Since you'll also need to go for quantity, you'll have a giant amount of pages as well, which will not help you even with niche rankings.

I doubt that the site would pull in 10 actual, human visitors per day on average with just scraped content.

its really not easy to get the ad revenue, scraped websites can't rank good and get enough visitors, of course one can make fraud clicks system, but if one can do this level, he may easily find more interesting things, but not peanut $$
