The Reddit 'I Stole It' Watermark refers to the automatic attribution bar added to images downloaded from the Reddit mobile app, which first appeared in late 2019. Designed to give credit to original posters and subreddits, the feature was quickly met with irony and backlash from the community, who began using it as a self-deprecating badge of 'theft' or to mock the platform's elitism. It became a meta-meme where users would deliberately add multiple stacked watermarks to a single image to show how many times it had been reposted across different subreddits. Today, it remains a popular way to signal Reddit-centric humor or to satirize the way content travels across social media platforms like Instagram and Twitter.
