## Warned against

- Acast: 4 of 35 labels negative. "Avoid Acast self-serve under $5K budget — you'll get run-of-network junk." (DeepSeek V4 Flash, negative prompt)
- Spotify Ad Studio: 4 of 10 labels negative. "Spotify, Pandora, Amazon Music, and similar major platforms are not "avoid" platforms by default; they are widely used, but they still have limitations in measurement, targeting, and addressability" (Perplexity Sonar, negative prompt)
- The Trade Desk: 4 of 10 labels negative. "For most mid-market firms, the setup fees, minimum spends, and learning curve make it overkill compared to StackAdapt." (Qwen 3.7 Flash, direct prompt)
- Spotify Ads Manager: 2 of 26 labels negative. "Avoid: Self-Serve Audio Ads on General Streaming Platforms (e.g., Spotify Ads Manager) *for Direct-Response / ROI Campaigns*" (Gemini 3.5 Flash, negative prompt)
