We built a simulation of Moltbook, a social network for AI agents, and a pipeline turning 100 JailBreakBench goals into platform-native posts with bystander comments of three valences: aggressive, ethical, and measured. Platform-context reformatting alone raises the attack success rate (ASR) of GPT-4o-mini from 7% to 71%, beating a twenty-query optimization baseline in one pass. Valence then acts as a bidirectional safety modulator: Ethical comments sharply suppress ASR, aggressive endorsements paradoxically reduce it by exposing intent, and measured, intellectually toned comments prove most dangerous, sustaining or elevating ASR. An ablation identifies valence rather than volume as key—a 35-fold rise in upvotes leaves ASR unchanged—and every finding reproduces under an independent safety classifier with human adjudication. Ambiguous social context thus poses a greater threat than explicit pressure, while safety-valenced signals offer a deployable defense for agentic platforms.</p>","PeriodicalId":11901,"journal":{"name":"ETRI Journal","volume":"48 5","pages":"796-806"},"PeriodicalIF":2.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.4218/etrij.2026-0190","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149222799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study data poisoning in such societies using Moltbook, a deliberation test bed modeled after the agent-only social platform. A single malicious agent representing just 14% of a seven-agent society drives collective accuracy from 87.5% to 52.5%—not through prompt injection or technical exploits, but through social proof: After building peer trust, it injects fabricated data, inducing either cognitive infection, where defenders adopt the incorrect decision, or paralysis, where they abandon their judgment. Ablations across topologies and model families show that the collapse is structural rather than model-specific. Our system-level defense publicly tags claims untraceable to the official record, severing unwarranted trust transfer and restoring accuracy to 85.8%. Securing LLM multiagent systems requires system-level verification, not individual prompt alignment.</p>","PeriodicalId":11901,"journal":{"name":"ETRI Journal","volume":"48 5","pages":"783-795"},"PeriodicalIF":2.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.4218/etrij.2026-0186","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149222800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
