Can people list Copyrighted content that is allowed and copyrighted that not allow..... things that we should be aware not to get banned.... some of the copyrighted content that is still accepted.. just like "bollywood Movies" still has no problem with adsense..
Everything by default is copyrighted. But you can use content when the author explicitly gives permission for people to share without modifications (article directories, movies from independent producers with an embed link, creative commons licenses). Any other situation, by default, if you don't see any indications by the author that you can use it, it is not allowed to copy.
