Welcome to the Q&A Forum

Hi again, Sorry for the misunderstanding. The links being from identical content should not be harmful to you - this sort of citation is fairly common, e.g. when a site has shared a piece of viral content like a video, infographic, tool (calculator etc.) or cited case study that others reproduce and link back to. I'd be far more concerned about the quality of the linking sites. I think the duplication question will also be even less of an issue if you remove the poor-quality links: identical citations from high-quality sources will pass as normal and not malicious liking activity.
