A friend of mine created a blog sometime ago and installed the auto-content plug-in. The blog stayed for one year and his adsense account was banned? What could be the reason? Does it mean that Google frowns at auto-blogging?
Autoblogs Survives till the time, they are'nt seen by Adsense support or inspector, and then what happens? Exactly what happened to you friend's account. Read their Policies here https://www.google.com/adsense/support/bin/answer.py?answer=48182&gsessionid=I7mXjMGk3Xnbl2iKGlbwbA , its clearly mentioned that "AdSense publishers may not display Google ads on webpages with content protected by copyright law unless they have the necessary legal rights to display that content."
This is a main reason. How "auto-content" plug-in create the contents? Isn't it just a content scraper / spinner? This will make the website low quality and that is a reason behind this. Google does not hate the plug-in itself but hates the low quality websites.
