AI Spam Filters Allegedly Block Legitimate Emails Based on Biased Keyword Detection

AlgorithmWatch tested spam filtering algorithms across Gmail, Yahoo, Outlook, GMX, and LaPoste. Their findings reportedly showed that Microsoft Outlook’s spam filter flagged emails based on specific keywords that led to racial and content-based biases blocking legitimate communications. Emails mentioning Nigeria or containing certain financial and sexual health terms were found to be disproportionately marked as spam.
