Manifold has leaked its users real names, email addresses, click activity, private markets, manalinks, ip addresses, and likely even its own Firebase admin key at one point. As far as I know, private messages and credit card numbers are the only user information that hasn't been leaked yet.
Resolves YES if Manifold leaks anyone's credit card number and they either confirm that it is real or I am able to charge it. NO by default at end of 2024.
Must be Manifold's fault. Sending your credit card number through PM and that getting leaked would resolve /CodeandSolder/will-manifold-leak-any-private-mess-8a94e1420f5a but it was your choice to use a likely-compromised channel so wouldn't resolve this market.
Anyone buying mana through standard Stripe interface and subsequently getting their credit card number leaked without knowing would count as a credit card leak.

I doubt Manifold will leak everyone’s credit card numbers in 2024. Big platforms usually rely on secure third-party processors, so they don’t even store raw card details. The bigger risks are more likely to be account phishing, password reuse, or general data breaches rather than a mass leak of credit cards. That said, no system is 100% safe—so I’d predict it’s unlikely, but using a virtual card or PayPal-style middleman is still a smart move just in case. For any concerns about payment security or managing transactions safely, I’ve reached out to Acima, and they were really helpful—so it might be worth contacting them for guidance.
Security features need to be explicitly tested as strategic decisions in block blast where players must carefully navigate risks to protect their resources and achieve their goals.
