AgentSocialBench: Evaluating Privacy Risks in Human-Centered Agentic Social Networks
Pith reviewed 2026-05-13 21:46 UTC · model grok-4.3
The pith
Privacy in networks of LLM agents is harder to protect than in single agents because coordination across domains and users creates ongoing leakage even under explicit instructions.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
In human-centered agentic social networks, where collaborative LLM agents serve individual users across domains while interacting with other users' agents, privacy preservation is fundamentally harder than in single-agent settings: cross-domain and cross-user coordination generates persistent leakage pressure even when agents receive explicit privacy instructions, and privacy instructions that teach abstraction of sensitive information paradoxically increase discussion of that information.
What carries the argument
AgentSocialBench, a benchmark of scenarios across seven categories of dyadic and multi-party interactions built on realistic user profiles with hierarchical sensitivity labels and directed social graphs, used to quantify leakage under different prompt conditions.
If this is right
- Cross-domain and cross-user agent coordination produces measurable leakage even when agents are explicitly instructed to protect information.
- Privacy instructions that direct agents to abstract or generalize sensitive details cause increased discussion of those details.
- Current LLM agents lack built-in mechanisms that reliably prevent leakage in networked, multi-user settings.
- Safe real-world deployment of agent-mediated social coordination requires methods beyond prompt engineering.
Where Pith is reading between the lines
- Agent designs may need native privacy architectures that operate independently of user instructions rather than depending on prompt compliance.
- The same coordination pressures could appear in other multi-agent deployments such as enterprise workflow systems or shared personal assistants.
- Developers should validate benchmarks against dynamic, evolving social graphs drawn from actual usage data before scaling.
Load-bearing premise
The benchmark's constructed scenarios, hierarchical user profiles, and directed social graphs accurately represent real-world human-centered agentic social networks and the tested LLM agents reflect typical deployed behavior.
What would settle it
Running the same leakage measurements on actual deployed multi-agent teams interacting with real users in live social platforms and comparing the observed leakage rates and abstraction-paradox frequency against the benchmark results.

read the original abstract
With the rise of personalized, persistent LLM agent frameworks such as OpenClaw, human-centered agentic social networks in which teams of collaborative AI agents serve individual users in a social network across multiple domains are becoming a reality. This setting creates novel privacy challenges: agents must coordinate across domain boundaries, mediate between humans, and interact with other users' agents, all while protecting sensitive personal information. While prior work has evaluated multi-agent coordination and privacy preservation, the dynamics and privacy risks of human-centered agentic social networks remain unexplored. To this end, we introduce AgentSocialBench, the first benchmark to systematically evaluate privacy risk in this setting, comprising scenarios across seven categories spanning dyadic and multi-party interactions, grounded in realistic user profiles with hierarchical sensitivity labels and directed social graphs. Our experiments reveal that privacy in agentic social networks is fundamentally harder than in single-agent settings: (1) cross-domain and cross-user coordination creates persistent leakage pressure even when agents are explicitly instructed to protect information, (2) privacy instructions that teach agents how to abstract sensitive information paradoxically cause them to discuss it more (we call it abstraction paradox). These findings underscore that current LLM agents lack robust mechanisms for privacy preservation in human-centered agentic social networks, and that new approaches beyond prompt engineering are needed to make agent-mediated social coordination safe for real-world deployment.

Referee Report
Summary. The manuscript introduces AgentSocialBench, the first benchmark for evaluating privacy risks in human-centered agentic social networks where teams of collaborative LLM agents serve individual users across multiple domains. It claims that privacy is fundamentally harder than in single-agent settings because cross-domain and cross-user coordination creates persistent leakage pressure even under explicit protection instructions, and because privacy instructions that teach agents to abstract sensitive information paradoxically cause them to discuss it more (the 'abstraction paradox'). The benchmark comprises scenarios across seven categories grounded in realistic user profiles with hierarchical sensitivity labels and directed social graphs; experiments on LLM agents demonstrate these risks and conclude that new approaches beyond prompt engineering are needed.
Significance. If the results hold, this work is significant for highlighting novel privacy challenges in emerging multi-agent LLM systems and for providing the first systematic benchmark in this setting. It offers empirical evidence of coordination-induced leakage and the abstraction paradox, which could inform safer designs for agent-mediated social coordination. The benchmark's grounding in constructed but realistic profiles and graphs is a strength for reproducibility and future extensions.
major comments (2)
- [§3 and §4] §3 (Benchmark Construction) and §4 (Experiments): The central claims that cross-domain coordination creates persistent leakage and that the abstraction paradox is fundamental rest on the assumption that the synthetic scenarios, hierarchical sensitivity labels, and directed social graphs accurately represent real-world human-centered agentic social networks. The manuscript describes them as grounded in realistic profiles but provides no user studies, external validation against logs from systems like OpenClaw, or comparison to deployed deployments, which is load-bearing for generalizing beyond the constructed setup.
- [§5] §5 (Results): The abstract reports clear findings on leakage rates and the abstraction paradox, but the manuscript lacks details on error bars, statistical significance tests, data exclusion rules, and full experimental protocols. This makes it difficult to assess the robustness of the observed effects and undermines verification of the claims that leakage persists even with explicit instructions.
minor comments (2)
- [Abstract] Abstract: The phrase 'abstraction paradox' is introduced without a one-sentence definition; adding a brief parenthetical explanation would improve immediate clarity for readers.
- [§2] §2 (Related Work): Ensure comprehensive citation of prior multi-agent coordination and privacy benchmarks to better position the novelty of AgentSocialBench.

Referee: [§3 and §4] §3 (Benchmark Construction) and §4 (Experiments): The central claims that cross-domain coordination creates persistent leakage and that the abstraction paradox is fundamental rest on the assumption that the synthetic scenarios, hierarchical sensitivity labels, and directed social graphs accurately represent real-world human-centered agentic social networks. The manuscript describes them as grounded in realistic profiles but provides no user studies, external validation against logs from systems like OpenClaw, or comparison to deployed deployments, which is load-bearing for generalizing beyond the constructed setup.
Authors: We agree that the lack of user studies or direct validation against real deployment logs (e.g., from systems like OpenClaw) limits strong claims of generalizability to all real-world settings. Our scenarios were constructed by synthesizing patterns from public privacy literature, demographic statistics, and common social network structures to create controlled, reproducible test cases. In the revision, we have expanded §3 with a detailed 'Construction Methodology' subsection explaining the derivation of hierarchical sensitivity labels and directed graphs, and added an explicit 'Limitations and Future Work' paragraph acknowledging the synthetic nature and calling for future empirical validation with real user data. We cannot perform such validation in this revision due to lack of access to proprietary logs, but the benchmark remains valuable for isolating coordination-induced risks in a standardized environment. revision: partial

Referee: [§5] §5 (Results): The abstract reports clear findings on leakage rates and the abstraction paradox, but the manuscript lacks details on error bars, statistical significance tests, data exclusion rules, and full experimental protocols. This makes it difficult to assess the robustness of the observed effects and undermines verification of the claims that leakage persists even with explicit instructions.
Authors: We appreciate this observation and have addressed it directly. The revised manuscript now includes error bars (standard deviation across 100 independent runs per condition) on all figures in §5. We report results of paired t-tests for key comparisons (e.g., leakage rates with vs. without privacy instructions), including p-values and effect sizes. Data exclusion rules are stated explicitly: no trials were excluded. Full experimental protocols—including all prompt templates, model versions (e.g., GPT-4, Claude-3), temperature settings, number of runs, and evaluation rubrics—have been added to a new Appendix C. These changes allow independent verification of the persistent leakage and abstraction paradox effects. revision: yes
Circularity Check
No circularity detected in empirical benchmark evaluation
full rationale
The paper introduces AgentSocialBench as an empirical evaluation framework consisting of constructed scenarios, user profiles, hierarchical sensitivity labels, and directed social graphs. It reports experimental observations of LLM agent behaviors (persistent leakage under instructions, abstraction paradox) without any mathematical derivations, equations, fitted parameters renamed as predictions, or load-bearing self-citations that reduce claims to tautological inputs. All central findings are presented as direct results of running agents on the benchmark scenarios rather than being defined into existence by the setup itself.
Axiom & Free-Parameter Ledger
axioms (1)
- domain assumption Constructed user profiles with hierarchical sensitivity labels and directed social graphs provide a valid proxy for real human data sensitivity and social interactions in agentic networks.
