## Warned against

- ClickCease: 24 of 37 labels negative. "ClickCease explicitly targets small businesses, freelancers, and small-to-mid agencies. Enterprises that need multi-account administration, deep integration, and scale should look at CHEQ's enterprise tier or a different vendor." (DeepSeek V4 Flash, negative prompt)
- ClickGUARD: 16 of 27 labels negative. "SMB-Focused Click Blockers (e.g., ClickGuard, FraudBlocker, ClickGuardian)... these services inflate threat metrics" (Qwen 3.7 Flash, negative prompt)
- Fraud Blocker: 8 of 18 labels negative. "SMB-Focused Tools (ClickCease, ClickGUARD, Fraud Blocker) ... have significant limitations for enterprises" (Kimi K2, negative prompt)
- Lunio: 6 of 57 labels negative. "Prices as a *percentage* of your ad spend. This is the opposite of predictable" (DeepSeek V4 Flash, budget prompt)
