Reddit After Roe: A Computational Analysis of Abortion Narratives and Barriers in the Wake of Dobbs

The 2022 U.S. Supreme Court decision in Dobbs v. Jackson Women's Health Organization reshaped the reproductive rights landscape, introducing new uncertainty and barriers to abortion access. We present a large-scale computational analysis of abortion discourse on Reddit, examining how barriers to access are articulated across information-seeking and information-sharing behaviors, different stages of abortion (before, during, after), and three phases of the Dobbs decision in 2022. Drawing on more than 17,000 posts from four abortion-related subreddits, we employed a multi-step pipeline to classify posts by information type, abortion stage, barrier category, and expressed emotions. Using a codebook of eight barrier types, including legal, financial, emotional, and social obstacles, we analyzed their associations with emotions and information behaviors. Topic modeling of model-generated barrier rationales further revealed how discourse evolved in response to shifting legal and cultural contexts. Our findings show that emotional and psychological barriers consistently dominate abortion narratives online, with emotions such as nervousness, confusion, fear, and sadness prevalent across discourse. By linking information behaviors, barriers, emotions, and temporal dynamics, this study provides a multi-dimensional account of how abortion is navigated in online communities.

Archiving and Replaying Current Web Advertisements: Challenges and Opportunities

Although web advertisements represent an inimitable part of digital cultural heritage, serious archiving and replay challenges persist. To explore these challenges, we created a dataset of 279 archived ads. We encountered five problems in archiving and replaying them. For one, prior to August 2023, Internet Archive's Save Page Now service excluded not only well-known ad services' ads, but also URLs with ad related file and directory names. Although after August 2023, Save Page Now still blocked the archiving of ads loaded on a web page, it permitted the archiving of an ad's resources if the user directly archived the URL(s) associated with the ad. Second, Brozzler's incompatibility with Chrome prevented ads from being archived. Third, during crawling and replay sessions, Google's and Amazon's ad scripts generated URLs with different random values. This precluded archived ads' replay. Updating replay systems' fuzzy matching approach should enable the replay of these ads. Fourth, when loading Flashtalking web page ads outside of ad iframes, the ad script requested a non-existent URL. This, prevented the replay of ad resources. But as was the case with Google and Amazon ads, updating replay systems' fuzzy matching approach should enable Flashtalking ads' replay. Finally, successful replay of ads loaded in iframes with the src attribute of "about:blank" depended upon a given browser's service worker implementation. A Chromium bug stopped service workers from accessing resources inside of this type of iframe, which in turn prevented replay. Replacing the "about:blank" value for the iframe's src attribute with a blob URL before an ad was loaded solved this problem. Resolving these replay problems will improve the replay of ads and other dynamically loaded embedded web resources that use random values or "about:blank" iframes.
