Some of my friend at Wangcyber forum are use some technique that they call as blog farming to increase their adsense income.i'm believe this is blackhat technique.but recently,google doesn't ban their account and their income are increase day per day.Are this technique doesn't against AdSense TOS? Fyi,they used Auto RSS feed to blog.And they make average 200-500 blogs per person.My question is,how can they provide a quality content when they using another web content using their auto RSS feed and how they manage their blog?
Well with blackhat.. it's a tough one but you can get banned.. (I posted something about this before) however, they don't either.. depends how aggressive the black hat is I guess. For using RSS feeds as content (and other people's content) it's fine, but make sure you add atleast *some* original content in your site
