Pink slime journalism is a practice where news outlets publish low-quality or inflammatory partisan articles, claiming to be local news networks. This paper examines the spread of pink slime sites on Facebook using public posts from Pages and Groups. We evaluate the trends of sharing pink slime sites on Facebook and patterns regarding the advertisements purchased by the parent organizations of the pink slime news networks. Our analysis discovers that while the number of pink slime posts on Facebook pages have decreased over the years, advertising dollars have increased. The increase in advertising dollars influences an increase in Facebook group posts. Further, the advertising expenditure increases during election years, but contentious topics are still discussed during non-election years. By illustrating the patterns and themes from US election years of 2020, 2022, and 2024, this research offers insights into potentially dangerous journalism tactics, and provides predictions for future US Presidential Elections.

翻译：“粉红粘液新闻”是指新闻机构以地方新闻网自居，发布低质量或煽动性党派文章的行为。本文通过分析Facebook公共主页与群组的公开帖文，研究了粉红粘液新闻网站在Facebook上的传播情况。我们评估了Facebook上分享粉红粘液网站的趋势，以及粉红粘液新闻网所属母机构购买广告的模式。分析发现，尽管Facebook主页上的粉红粘液帖文数量逐年减少，但其广告支出却在增加。广告支出的增长推动了Facebook群组帖文数量的上升。此外，广告支出在选举年份会显著增加，但在非选举年份仍会持续讨论争议性话题。通过展示2020年、2022年和2024年美国选举年的传播模式与主题特征，本研究揭示了潜在危险的新闻操作策略，并对未来美国总统选举的舆论态势作出预测。
