I suggest you do not put content from other pages in your site. Even if google do not penalize your site for the duplicate content, you still are not going to get any traffic on pages where you put copied content. To get traffic from google and other search engines, you need unique content
They won't just penalize you but they won't probably assign search ranking for the contents placed on your site. Since you place a url to link back to the original content, that would not create any other issues.
Ehm..ehm.. some one talk about my website project (www.quickcontentwizard.com). Yes, it's generate funny english both for content generator and article rewriter, it's purposed for SEO only, not for human reader. It's just my unserious experiment with 3 days work of coding. But with this tool, now I have hundreds of junk blogs. I build also Wordpress plugin for content generator and article rewriter for my personal purpose, not publicly yet, I can make hundreds article in seconds with just one click. And I have conclusion that, after a year, I put all the garbage article into my blog. I still have moderate adsense income from my junk blogs. But, I think the income is not so optimal with that kind of article. I have also some serious blogs, they seems have more stabil income with adsense from search engine traffic (so you think yourself). And I put it all in one adsense account. My adsense account still safe until now, and hundreds of my blogspot blogs still untouchable by goole (safe and all get indexed by google and some have PR). (actually, i made this tool because english is not my native language.. so thanks for all comments here
you won't get banned for this, providing you are not a spam site and have at least some original content on your site. You will however suffer from the duplicate content rule which means that the site where the article was first published and/or the site with the highest page rank will have the article listed in Google. This is stop there being thousands of search results with the same article.
I think you are still at risk if any of your sites ever get noticed by a human and reported as spam...... if google does a manual review you might lose everything, including the adsense account.
If thats the ONLY content on your pages it will be labeled duplicate and ignored. If you have just a little of the content and a lot of your own opinions, feedback, corrections etc you might avoid being considered spam.
Photos or content, dont copy from others without permission. It will have other treatment if you do on the top of google dupe filtering. Even if you have permission, google doesnt know it and will simply rank you lower. Rewording content is an act of plagiarism if you do it without permission. So refrain from such practices. Haha, yes, and with zero visitors. But do play safe and get permission before copying, otherwise, your site will have content and you will be in court.
