Abstrakt: Social media bot detection research exhibits imbalances across platforms, languages, and detection levels. Addressing these gaps, this study focuses on comment-level bot detection within Polish Reddit communities. We describe in detail the construction of a comprehensive dataset (~40,000 comments, 58% bot-comment prevalence), which provides labels for subsequent model training. Polish Reddit is inherently multilingual; we therefore take advantage of the linguistic signals, treating the language composition of a comment as a feature in its own right. We develop novel platform-specific, language-specific, and culturally informed features, and train comment-level classifiers from multiple model families on our manually annotated dataset. Temporal evaluation on 2025 data indicates strong generalization, while also revealing model-specific differences and a late-period recall decline suggesting shifts in bot behavior. As a step toward model interpretability, we examine cross-model feature importance and directional effects using SHAP values. Finally, we complement our quantitative findings with a qualitative characterization of the Polish Reddit bot ecosystem. Overall, this study provides an important baseline for an underexplored setting and contributes to an open discussion on how to approach detection where data is linguistically mixed.
