The message that you have received was the bot launched by alexmove to help tracking the plagiarism on the platform. Sharing the content by Dtube allows to publish the same post on several platforms, so the bot was easily making the mistakes, but it's NOT the plagiarism. Your content is original. I'm sorry for the inconveniences. The bot was already turned off on Dtube (after a few hours of testing) and it was suggested that it should be improved and tested in some closed environment before launching again.
