I had the same problem with Duplicated material. Hubpages will not allow you to publish a hub that is too similar to any other article anywhere else on the web no matter whose article it is. It does not matter if you yourself havwe never published it. Someone else already has. That is why when I write about popular topics like Hitchcock or Columbo I write about favourite aspects or reactions to the episodes as I'm the only person with thosereactions.
The time I had a problem with duplication is when I tried to publish a hub on my mother's artwork. Mom is an award-winning member of the Canadian Society of Painters of Watercolour and has an interesting biography I wanted to share as a new member of the website to let others know about my family.
PROBLEM: As an artist, her biography and best known artwork is already discussed and shown elsewhere on the web. I even tried to write a hub on her account-she joined to follow me, she's not a writer herself. But even when I tried to create a hub with her as a separate hubber, this was not allowed. we were told tha even though Mom held the copyright for this material, hubpages will not allow duplicate content. That I found surprising considering Mom owns the copyright for her images. But that is the way hubpages works. So I deleted the hub and wrote a biography for her on her profile, even though she isn't a hubber.
And for those of you criticizing Cardisa-not eveyone who answered the question did, but some did- on participation-I see him listed in forums al lthe time and leaving comments on people's hubs. He is particpating. Don't asume he isn't participating just because he is talking about hubscore. He is new like I am. We don't know something, so we ask a question. It doesn't mean that the person asking the question wants to focus on his own hubs only. Cardisa is actually quite an intelligent person.
