If we look at the Vulture Bee article, it cites a couple semi-relevant journal articles (which do exist but are not exactly on point for a general citation), but then it inflates the number of citations pointlessly by citing multiple pop news articles that all cite one of the previously cited research papers, and some of which just blogspam link to the other useless popular science magazine citations.

Sometimes this is done despite the existence of reliable public databases of such documents available through universities, foundations, and governments. Then there is the link rot problem which gets worse over time.
