• Abstract summary: We make the first step towards quickly detecting and red-flaging websites that potentially manipulate the public with disinformation. We build a machine learning model based on multilingual text embeddings that first determines whether the page mentions a topic of interest, then estimates the likelihood of the content being malicious. Our system empowers internal teams to proactively blacklist unsafe content, thus protecting the reputation of the advertisement provider.

• Abstract: In today's world, the presence of online disinformation and propaganda is more widespread than ever. Independent publishers are funded mostly via digital advertising, which is unfortunately also the case for those publishing disinformation content. The question of how to remove such publishers from advertising inventory has long been ignored, despite the negative impact on the open internet. In this work, we make the first step towards quickly detecting and red-flagging websites that potentially manipulate the public with disinformation. We build a machine learning model based on multilingual text embeddings that first determines whether the page mentions a topic of interest, then estimates the likelihood of the content being malicious, creating a shortlist of publishers that will be reviewed by human experts. Our system empowers internal teams to proactively, rather than defensively, blacklist unsafe content, thus protecting the reputation of the advertisement provider.

  We show that ad networks have withdrawn mostly from unpopular misinformation websites with very few visitors. We show that ad networks continue to place advertisements of legitimate companies next to misinformation content. In fact, major ad networks place ads in almost 400 misinformation websites of our dataset.

  We propose and investigate the prevalence of a new means for discrimination in job advertising. It combines both targeting and delivery -- through the disproportionate representation or exclusion of people of certain demographics in job ad images. We use the Facebook Ad Library to demonstrate the prevalence of this practice.

  We study Facebook and investigate key gaps in our understanding of problematic online advertising. We find that older people and minority groups are especially likely to be shown such ads. Given that 22% of problematic ads had no specific targeting from advertisers, we infer that ad delivery algorithms played a significant role in the biased distribution of these ads.

  We build a six-year dataset on the Italian vaccine debate and adopt a Bayesian latent space model to identify narrative and selection biases. We found a nonlinear relationship between biases and engagement, with higher engagement for extreme positions. Analysis of news consumption on Twitter reveals common audiences among news outlets with similar ideological positions.

  This paper proposes a novel system for detecting, processing, and warning users about misleading content online. By training a machine learning model on an existing dataset of 32,000 clickbait news article headlines, the model predicts how sensationalist a headline is. It interfaces with a web browser extension which constructs a unique content warning notification based on existing design principles.
