Opinion

DAVID ANGEL SIFUENTES, Case No. 25-cv-04479-JST

Plaintiff, ORDER DISMISSING THE SAC v. Re: ECF Nos. 23, 28 Defendant.

Before the Court is Defendant Meta’s motion to dismiss Plaintiff David Angel Sifuentes’s Second Amended Complaint (“SAC”). ECF No. 23. The Court will grant the motion and dismiss the SAC without leave to amend. On May 27, 2025, Sifuentes filed this action against Meta, alleging that it had failed to notify him that his personal information and that of his Facebook friends had been compromised in a “massive data breach” that occurred in 2021. ECF No. 1 ¶ 1. He subsequently filed a First Amended Complaint (“FAC”) on June 10, 2025. ECF No. 5. Magistrate Judge Alex G. Tse granted Sifuentes’s application to proceed in forma pauperis but screened and dismissed the FAC under 28 U.S.C. § 1915(e)(2). ECF Nos. 10, 11. Sifuentes filed this SAC on July 21, 2025, which Judge Tse screened without dismissing on July 23, 2025. ECF No. 14. The SAC alleges thirteen causes of action: (1) violation of the Fair Credit Reporting Act; (2) negligence (under Michigan law); (3) invasion of privacy (under California Law); (4) breach of express contract (under California law); (5) breach of implied contract (under California law); (6) violation of California’s Unfair Competition Law; (7) violation of California’s Consumer Legal of Michigan’s Consumer Protection Act; (10) bailment (under California law); (11) violation of Michigan’s Identity Theft Protection Act; (12) fraud (under California law); and (13) trespass to chattels (under California law). Meta filed a motion to dismiss on September 26, 2025. ECF No. 23. Sifuentes opposed on October 6. ECF No. 25. Meta replied on October 17. ECF No. 26. Sifuentes moved for leave to file a sur-reply on October 28. ECF No. 28. Meta opposed the motion for leave on December 1. ECF No. 38. Sifuentes also attached to his opposition to the motion to dismiss a “cross-motion for summary judgment and opposition to defendant’s motion to dismiss.” ECF No. 25 at 7. He later filed a “notice of motion and motion for summary judgment” separately, including only an outline of the arguments he expected to make. ECF No. 35. Meta opposed the summary judgment motion on December 8, 2025. ECF No. 39. Sifuentes then filed an amended motion for summary judgment. ECF No. 40. The Court denied Sifuentes’s summary judgment motions by separate order. ECF No. 41. Sifuentes is an acknowledged serial litigant who has been placed on restricted filing status in both the Eastern and Western Districts of Michigan. Sifuentes v. Twitter Inc., No. 1:23-CV- 981, 2023 WL 8818095, at *4 (W.D. Mich. Nov. 30, 2023), appeal dismissed, No. 23-2066, 2024 WL 2887907 (6th Cir. May 31, 2024), and motion for relief from judgment denied, No. 1:23-CV- 981, 2025 WL 294259 (W.D. Mich. Jan. 21, 2025), appeal dismissed sub nom. Sifuentes v. Midland Cnty., MI 42nd Cir. Ct., No. 24-2063, 2025 WL 3502509 (6th Cir. Nov. 5, 2025). The Court has jurisdiction under §§ 1331, 1332, and 1367. To survive a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), a complaint must contain “a short and plain statement of the claim showing that the pleader is entitled to relief.” Fed. R. Civ. P. 8(a)(2). “[A] complaint must contain sufficient factual matter, accepted as true, to ‘state a claim to relief that is plausible on its face.’” Ashcroft v. Iqbal, 556 allegations need not be detailed, but facts must be “enough to raise a right to relief above the speculative level.” Twombly, 550 U.S. at 555. In determining whether a plaintiff has met the plausibility requirement, a court must “accept all factual allegations in the complaint as true and construe the pleadings in the light most favorable” to the plaintiff. Knievel v. ESPN, 393 F.3d 1068, 1072 (9th Cir. 2005). However, mere legal conclusions and “[t]hreadbare recitals of the elements of a cause of action” are “not entitled to the assumption of truth.” Iqbal, 556 U.S. at 678–79. As here, a “document filed pro se is to be liberally construed and a pro se complaint, however inartfully pleaded, must be held to less stringent standards than formal pleadings drafted by lawyers.” Erickson v. Pardus, 551 U.S. 89, 94 (2007) (internal quotations and citation omitted). A. Plausibility Each of Sifuentes’s claims stems from his allegation that his personal information was “compromised” by a breach of data maintained by Facebook. ECF No. 12 ¶ 10. The basis for Sifuentes’s allegation is two attached documents: (1) a screenshot of a notification from Apple, received by Sifuentes on May 20, 2025, indicating that the email and password he used for his Facebook account had been involved in a data breach, and (2) a news article describing a cyberattack in April of 2021 wherein cybercriminals accessed personal information belonging to “more than half a million Facebook users.” ECF No. 5 at 24, 27; ECF No. 12 ¶ 13.1 The article states that cybercriminals aquired Facebook identities, full names, birth dates, locations, and email addresses. ECF No. 5 at 27. Sifuentes has failed to allege facts rendering his theory plausible. The 2025 Apple notification merely states that the password used for his Facebook account appeared in a breach— 1 Although these documents are attached to the FAC, but not the SAC, the Court considers them as incorporated by reference into the SAC. See ECF No. 5 at 24–33; Williams v. Cnty. of Alameda, not that the breach was one targeting Facebook. ECF No. 5 at 24. Moreover, the news article Sifuentes attached does not state that passwords were included in the 2021 breach. Compare ECF No. 5 at 24 with id. at 27. Rather, the article states that the 2021 breach involved “scrap[ing]” users’ profiles—but passwords are not published on users’ profiles. Id. at 27–28. Moreover, as Sifuentes readily admits, he used the same password for “multiple” other accounts. ECF No. 12 ¶ 16; ECF No. 5 at 24. The fact that Sifuentes received the notification in 2025 further undermines his claim that it related back to the 2021 Facebook breach. ECF No. 5 at 24. Sifuentes’s attached article states that individuals can confirm that they were impacted by the 2021 breach using a website. ECF No. 5 at 27. Sifuentes does not allege that he used this website to confirm that he was impacted. And he alleges no other means by which he attempted to discover whether his information was included in the 2021 breach and no facts suggesting that it was. Sifuentes alleges that because of the breach, his “Facebook account was hijacked, his personal information and that of his contacts were exposed, [and] unauthorized communications were sent from his account.” ECF No. 12 ¶ 2. He does not explain how or to whom “his personal information and that of his contacts were exposed.” He likewise does not provide any detail about the “unauthorized communications” and “Facebook friend requests” sent from his account, even though those details are presumably readily accessible to him. Id. ¶¶ 2, 15. Nor does he explain why the cybercriminals behind the 2021 Facebook data breach would be interested in sending Facebook friend requests on his behalf. Sifuentes also attaches a screenshot of an apparent phishing email. ECF No. 5 at 33. He provides no grounds for the Court to conclude that this phishing email was related to the alleged breach in any way. First, it involved a different email address than the one listed in the notification from Apple. Id. Second, it was received on June 2, 20
