Hi. I worked for a client through Odesk, he asked for three Poker-related articles and I delivered them (basically they were written by another content writer whom I hired).
The client replied back to me that the articles were not unique, one had 33% unique content while the other had 66% unique content. He requested a refund and I refunded him the amount and also apologized for the duplicate content.
They were just 300-words articles.
So now my question is - suppose this client continues using these articles on a live website and gets sued for it, can I land into any trouble? The client already found out that the content was not unique plus I also refunded him the amount so basically there is no contractual obligation anymore...
