## Warned against

- Forter: 13 of 33 labels negative. "Enterprise platforms (Signifyd, Forter, Riskified) often require sales calls and custom contracts averaging $80K+/year" (Kimi K2, direct prompt)
- Sift: 7 of 44 labels negative. "Can be complex to configure; occasional false positives requiring manual review. Not ideal for very small teams due to setup overhead." (Grok 4.1 Fast, negative prompt)
- Riskified: 8 of 29 labels negative. "avoid relying strictly on a Chargeback Guarantee (Riskified, Signifyd) as your false decline rate will silently eat your profits" (Gemini 3.5 Flash, negative prompt)
- Signifyd: 8 of 43 labels negative. "Signifyd's public terms define eligible chargebacks narrowly... That's a reason to get the exact coverage schedule and exclusions in the signed agreement—not, by itself, a reason to avoid Signifyd." (GPT-6 Luna, negative prompt)
