Cara's Scraper Now Helps Build Artist-Protection Tool

Cara's Scraper Now Helps Build Artist-Protection Tool

Key takeaway

  • Cara, an artist-focused social app, suffered three scrapes in August 2025.

  • The first scraper later apologized and now helps build a protection tool.

  • The tool, Lantern, scans AI datasets and notifies artists of unauthorized use.

3 Key Points

  1. What happened

    Since August 13, Cara, an image-sharing app for artists, was hit by three major scrapes. The first pulled a 12-terabyte archive of 12 million works, the second grabbed about 8.5 million links, and the third obtained 123,000 images. The original scraper, who goes by "Heft," later apologized and is now collaborating with founder Jingna Zhang on a new open-source tool called Lantern.

  2. Why it matters

    Artists migrated to Cara to avoid having their work used to train AI without permission, but scraping remains nearly impossible to prevent. Zhang says laws haven't caught up, and the attacks spiked server fees and alarmed creators, some of whom deleted their portfolios. She also notes that bigger platforms get scraped more, so leaving Cara doesn't necessarily make artists safer.

  3. What to watch

    Lantern lets artists create a "one-way fingerprint" for their images without storing them on the platform. It regularly scans new publicly available AI image datasets and notifies artists if their work appears, so they can request removal or submit a takedown notice. Zhang has raised more than $100,000 of her $120,000 GoFundMe goal for legal fees.

Context & Analysis

The scrapes of Cara highlight a structural vulnerability: no website can fully prevent automated data collection, and current laws offer limited recourse. Zhang, who is also part of class actions against AI companies, sees the attacks as part of a broader pattern where "getting attacked by AI is just going to become so, so commonplace." The irony that her initial attacker now helps build a defense tool underscores how individual ethics can vary in the AI training debate.

Heft's reversal came from witnessing the emotional impact on artists, many of whom had moved to Cara specifically to avoid AI exploitation. His technical insight that "no site can be made truly 'unscrapable'" led to the after-the-fact approach of Lantern, which focuses on detection and notification rather than prevention. This pragmatic workaround reflects the current regulatory vacuum, where tools like Glaze only mask style but cannot stop scrapes themselves.

For artists, the takeaway is nuanced: leaving Cara doesn't guarantee safety, as "bigger platforms get scraped more." Lantern offers a way to regain some control, but its effectiveness depends on widespread adoption and the cooperation of dataset hosts like Hugging Face, which declined to remove URLs citing that no copies were hosted there. The open-source nature of the tool means anyone can contribute, potentially making it a community-driven countermeasure in an ongoing arms race.

FAQ

What is Lantern and how does it work?
Lantern is an open-source tool that lets artists create a "one-way fingerprint" for their images without storing them on the platform. It regularly scans new publicly available AI image datasets and notifies artists if their work appears, so they can request removal or submit a takedown notice.
What happened during the scrapes of Cara?
Three scrapes occurred starting August 13. The first pulled a 12-terabyte archive of 12 million works, the second grabbed about 8.5 million links plus metadata, and the third obtained 123,000 images with personal information. These spiked server fees and alarmed creators.
How did the original scraper become a collaborator?
After facing backlash and seeing artists' distress, the scraper, known as "Heft," apologized and deleted his dataset. He then joined Cara's Discord as a troubleshooter and began collaborating with Zhang on Lantern.
