I guess plagiarism is a real concern for the community owned content rewarding systems everywhere on the internet. In order to gain those quick bucks, there would be a lot of people who would want to copy from other main stream media. Some times the intentions may not be wrong but the copying is still a bad behavior. I am not an expert on plagiarism. But as the parent community have a system of reporting the copy pasted content to the account which is used only to penalize, we can also have something on similar lines. Thank you @fireguardian for always encouraging me and to make me think.
