That's how the mainstream media pushes bad news sources as well. They all do it. They will let some smaller source start an article, and then either reference that as a valid source, or merely mostly copy it with listing sources as anonymous. Sometimes articles will drop at the same and these places will reference each other as sources, making the whole thing circular. My question is, did you dig deep  enough to make sure this wasn't the case? Secondly, assuming they are just gambling with bad sources, why give them a free pass? It's dishonest, it lacks integrity. Most people don't read past the headline - ideas get cemented in their head that way. It's an easy way to steer an audience.
