- Slack: 8 of 8 labels negative. "Slack, Discord or social-media groups as your only permanent customer community" (GPT-5.6 Sol, negative prompt)
- Facebook Groups: 5 of 6 labels negative. "The biggest “avoid” category is usually *consumer/social platforms used as a community home*—especially Facebook Groups" (Perplexity Sonar Pro, negative prompt)
