A few years ago, most content mills (HubPages, Zujava, InfoBarrel, etc) *REQUIRED* you to have an AdSense/Chitika account to make money through all displayed ads on these websites. You typically had to either put your ad code in your account's settings, or at the very least provide them with your PUB ID.
However, these days most of these sites only require your PayPal address, and they would send you the money 30 to 60 days after reaching a certain threshold. No more messing around with AdSense/Chitika accounts.
I am developing an article community, but forcing my writers to apply or have an AdSense account (or Chitika) really bugs me. Would anyone know how these guys are doing the above? I'm at a loss. No clue if they are messing with some advanced PayPal or AdSense API setting or what.
