SAHG: Sector-Anisotropic Hyperbolic Graph Model for Social Bot Detection

arXiv:2605.30166v1 Announce Type: cross Abstract: LLM-driven social bots can generate fluent, human-like text, reducing the discriminative advantage of content-based detection alone. However, coordinated campaigns still leave relational patterns -- interactions, behavioral similarity, shared neighborhoods, community positions, and coordinated activity -- that graph-based methods can exploit. Existing graph detectors face two challenges when exploiting such evidence. First, Euclidean GNNs distort hierarchical and scale-free social graphs; while hyperbolic geometry addresses this volume-growth m

Why this matters
Why now

The proliferation of advanced LLMs has significantly empowered social bots, making their detection more challenging through traditional content analysis methods.

Why it’s important

This research offers a new computational approach to identify sophisticated AI-driven disinformation and manipulation, which is critical for maintaining robust social and political discourse.

What changes

The ability to more accurately identify LLM-driven social bots shifts the battlefield from content analysis to relational patterns and network geometry for detection.

Winners
  • · Social media platforms
  • · Cybersecurity firms
  • · Democratic institutions
  • · Research in graph neural networks
Losers
  • · State-sponsored disinformation campaigns
  • · Malicious actors using AI bots
  • · Traditional content-based bot detection methods
Second-order effects
Direct

Improved detection capabilities will disrupt large-scale coordinated influence operations on social media.

Second

Adversarial AI development will accelerate to create bots that can evade these new graph-based detection methods.

Third

The arms race between AI bot development and detection will continue, potentially leading to more advanced and covert forms of information warfare.
