Anonymized Developer Cases
Seamless approval for developer monetization tools
Switched my developer API platform from Stripe to Polar for billing open-source packages. Onboarding was completely self-serve. No company registration required for initial tiers. Payouts processed on-chain and via Stripe Connect.
// Great for solo developers selling SaaS subscriptions or API keys without wanting to set up a full LLC on day one.
Card testing bots spammed my AI generator and got me banned
Launched an AI avatar generator on Product Hunt. Within 12 hours, a botnet hit our credit card form with 4,000 card testing attempts. 80 disputes rolled in the next day. Stripe automated system flagged it as fraud and closed the account instantly.
// Always set up Cloudflare Turnstile or Stripe Radar rules for custom rate limits before launching. Stripe support wouldn't help until I escalated on Twitter.
Atlas LLC banned for using personal utilities as business address
Registered Delaware LLC via Atlas from Romania. Used the default registered agent address for Stripe. Stripe flagged it during KYC review as an unverified address and closed the account after Romanian passport verification.
// Stripe requires physical verification. Make sure you have a real utility bill or bank statement associated with your virtual address/LLC, or they'll trigger a manual suspension.
