Meta has filed a motion to dismiss a lawsuit alleging it illegally downloaded thousands of adult films to train AI models. The company argues the downloads were for personal use by employees and contractors, not corporate AI training.

Meta Faces Copyright Lawsuit Over Alleged AI Training Data

Meta is fighting back against a high-stakes copyright lawsuit that accuses the tech giant of illegally downloading thousands of adult films to train its artificial intelligence models. The case, filed by adult film companies Strike 3 Holdings and Counterlife Media in July, seeks $359 million in damages and alleges that Meta systematically pirated nearly 2,400 pornographic videos since 2018

Strike 3 Holdings, which produces content under brands including Vixen, Blacked, and Tushy, claims it discovered illegal downloads on Meta's corporate IP addresses and through an alleged "stealth network" of 2,500 hidden IP addresses

Meta's Defense Strategy

In a motion to dismiss filed Monday, Meta vehemently denied the allegations, calling them "nonsensical and unsupported" and based on "guesswork and innuendo"

Meta's primary defense centers on the scale and timing of the alleged downloads. The company points out that only 157 of Strike 3's films were allegedly downloaded using Meta's corporate IP addresses over seven years, averaging roughly 22 downloads per year across 47 different addresses

. This "meager, uncoordinated activity" suggests individual employees downloaded content for personal use rather than systematic corporate data collection, Meta argues

Timeline and Technical Arguments

Meta emphasizes that the alleged downloads began in 2018, approximately four years before the company started researching "Multimodal Models and Generative Video," making it implausible that the downloads were intended for AI training

2

. The company also notes that its terms of service explicitly prohibit generating adult content, contradicting the premise that such materials would be useful for AI training

The tech giant argues that with "tens of thousands of employees" and "innumerable contractors, visitors, and third parties" accessing the internet at Meta facilities daily, the downloads could have been made by anyone from guests to repair personnel

. Meta specifically cited one case where a contractor allegedly downloaded content at his father's house, describing these as "plainly indicative of personal consumption"

Broader Implications for AI Industry

The case highlights growing scrutiny over how tech companies acquire training data for AI models. Meta has faced similar copyright lawsuits from book authors whose works were allegedly pirated to train the company's Llama model

4

. Legal experts suggest that if Meta's defense strategy succeeds, it could create a significant precedent for future AI training data cases.

Dermot McGrath, co-founder of venture capital firm Ryze Labs, noted that Meta's approach of denying any use of the material in model training avoids having to argue fair use or justify inclusion of pirated content. However, he warned this could "open a massive loophole" that might "effectively undermine copyright protection for AI training data cases"
