I'm running a facebook news page and I'm getting a bit of traffic. I am rewriting news articles, posting them to my site, and sending traffic to it from facebook. I've realized that a lot of big and small sized pages are copy+pasting day old news articles from other sites and still using adsense. Could I deindex my page from search engines and use copied articles without the risk of getting my adsense account banned? I've been spying on these pages and they have been doing this for a very long time. Once in a while they will throw up an article that can't be found in the search engines but 95% of them are straight up copied. Thanks!
