Chicago Man’s Defamation Suit Against Meta Dismissed Over AI-Generated Errors

Core Event: Court Throws Out D’Ambrosio’s Claim Against Meta
A Chicago resident, Nikko D’Ambrosio, filed a defamation lawsuit alleging that Facebook (Meta) profited from disparaging posts about him in the “Are We Dating the Same Guy” (AWDTSG) group. The suit, which named 27 women, one man and several platforms, was dismissed by U.S. District Judge David Hamilton after the judge identified AI-generated mistakes and fictitious citations in the plaintiff’s brief. The dismissal was entered in May 2025; D’Ambrosio appealed two months later.
Background & Context: AWDTSG Groups and Prior Litigation
AWDTSG groups are Facebook communities where members crowdsource “red flags” or “tea” about men they are dating. D’Ambrosio’s complaint claimed that the group’s negative characterizations—such as “clingy” and “psycho”—caused reputational harm and that Meta derived revenue from the content. Earlier attempts to sue group moderators, individual posters, GoFundMe and Meta had already failed after multiple revised complaints. In 2024, while the case was pending, D’Ambrosio was sentenced to a year in prison for tax fraud, a conviction highlighted by his former attorney Christopher Grohman.
Key Figures & Groups
- Nikko D’Ambrosio – Plaintiff, Chicago man accused of harassing behavior in the AWDTSG group.
- Aaron Walner – Attorney at Marc Trent’s law firm who drafted the AI-assisted brief.
- Marc Trent Law Firm – Law firm that promotes AI-driven case management on its website.
- Judge David Hamilton – U.S. District Judge who dismissed the case and criticized the AI usage.
- Rob Freund – Attorney who first flagged the AI-generated errors on X.
- Christopher Grohman – Attorney who defended D’Ambrosio in the tax-fraud case.
Data & Statistics
- Plaintiffs named: 27 women, 1 man, multiple platforms.
- Dismissal date: May 2025; appeal filed August 2025.
- Tax-fraud sentence: 1 year imprisonment in 2024.
- AI usage claim: Judge Hamilton noted “numerous mistakes and fictitious quotations” in the brief, a pattern he described as “sloppy work” that appears “fairly often” in recent filings.
Official Statements & Responses
Judge Hamilton concluded that D’Ambrosio’s brief failed to cite any relevant legislative findings and that the alleged AI-generated citations undermined the claim that Meta violated right-to-publicity laws. The court ordered Walner, Trent and D’Ambrosio to answer for the AI-generated filings or face sanctions. Marc Trent’s website asserts that its AI tools “automate document review, flagging key information and identifying relevant case law in seconds,” emphasizing that the technology is employed to win cases. The firm declined to comment when contacted for comment on the dismissal.
Criticism & Opposition
Legal commentators have described the incident as part of a broader “legal-world epidemic” of AI misuse, noting that judges’ patience is wearing thin as AI-generated filings proliferate. Attorneys cited in the sources have previously blamed technical difficulties or personal emergencies for filing errors, but the judge’s remarks suggest a systemic issue rather than isolated mishaps.
Verbatim Quotes
- “The brief included no citation to any legislative findings, let alone any including the statute’s targets as the brief asserted... These mistakes and fictitious quotations bear the hallmarks of the misuse of generative artificial intelligence.” — Judge David Hamilton
- “We see such sloppy work in briefs fairly often, and almost always let it pass without comment as we try to focus on the merits of appeals,” — Judge David Hamilton
- “I don’t mean this to disparage Nikko in any way, but as you can see from his educational records, he is not the most sophisticated human being,” — Christopher Grohman, attorney
- “Gone are the days of sifting through mountains of paperwork. Our AI tools automate document review, flagging key information and identifying relevant case law in seconds,” — Marc Trent Law Firm website
Conflicting Reports & Gaps
The only response from Marc Trent’s firm is a general statement about AI use; no specific comment on the alleged errors was provided. No rebuttal from Meta or the AWDTSG group moderators appears in the sources.
What’s Next: Potential Sanctions and Ongoing Appeal
The court has warned that failure to address the AI-generated filings could result in sanctions against Walner, Trent and D’Ambrosio. The appeal, filed in August 2025, will determine whether the dismissal stands or if the case can be revived on procedural grounds. The outcome may influence how courts regulate AI-assisted legal drafting moving forward.
