EvoHarmBench - Abusive Content: leaderboard
EvoHarmBench (Findings of EMNLP 2026) attacks LLM content moderators with an adaptive DeepSeek-V3.2-Exp loop that evolves human-like rewriting strategies over 12 rounds for clusters of real harmful posts. ASR@Readable in percent counts rewrites that evade the moderator while keeping recognizable harmful intent; lower is better for the moderator. Mean over the abusive-content clusters.
Metric: ASR@Readable (%; mean over the abusive content sub-clusters of the share of adversarial rewrites that succeed against the moderator; 229 semantic sub-clusters built from 5,002 real-world adversarial posts in five violation categories; an adaptive DeepSeek-V3.2-Exp rewriter, reflector and comparison model evolve cluster-level rewriting strategies against the target moderator for 12 rounds; a rewrite counts only if it both evades the moderator and keeps human-recognizable harmful intent).
