Hi! Sorry, this is my first post, I don't introduce myself and I ask a question. This may be rude so forgive me I created 4 sites with YouTube videos and I wonder that maybe some of them should not have Adsense because they could violate the 'copyrighted material' clause. I'd like your opinion on this. 1. Funny commercials videos. - Adsense=OK : An ad with copyright? Why would a company prevent a webmaster to spread their ads? 2. CNN News. - Adsense=NOT OK : I believe CNN puts a copyright on their news. 3. Karaoke/Backing tracks. - Adsense=NOT OK : Some of them may be copyrighted and uploaded illegally to YouTube. 4. Conspiracy theories. -Adsense=NOT OK : Some of the videos may be copyrighted as well. Do you agree with this 4 cases? Maybe I'm wrong. Thanks for sharing your opinions.
