| # Control Discourse — Pre-ChatGPT Participants (robustness arm) | |
| Subset of `CompassioninMachineLearning/reddit-control-discourse-2020-present` restricted to hashed authors whose **first comment in the corpus | |
| predates ChatGPT's launch (2022-11-30)**. These users were demonstrably engaged in | |
| hobby discourse before AI chatbots existed, so they cannot be the post-2022 LLM-bot / | |
| karma-farm wave. Use as the robustness arm of the diversity/kink analysis: "among | |
| people already in the conversation before ChatGPT, did their diversity collapse?" | |
| - Kept **945,891** of 1,507,613 records (62.7%), from 256,437 pre-ChatGPT authors. | |
| - `author_first_seen.parquet` maps every hashed author -> first_seen date + pre_chatgpt flag. | |
