i wonder if i use wordpress autoblog by just subdomain to earn from adsense. will i get chance to be banned?
Google bans a lot of things for a lot of reasons.... and most of the time they don't tell you. Autoblogs don't create much value, and google is all about value. So not only might you get banned... who knows... you probably won't get much per click as you will never achieve much of a ranking. The proper way to use RSS is to feed in stories that are of specific interest to your users. Creating an entire site based on RSS pulls doesn't really create value for anyone.
