As answered by people managing GPTZero and ProtectFlow.
ProtectFlow's answer:
ProtectFlow combines AI scanning with people. AI searches 24/7, a specialist also searches manually, and a copyright specialist reviews every notice before it is sent, so notices reach the right recipient with the right legal basis. Notices are filed in ProtectFlow's name, not the creator's. And it works in English, Spanish, Portuguese and Russian, with crypto-only payments.
ProtectFlow's answer:
Most takedown services are fully automated and English-only. ProtectFlow is for creators who want a team behind their case: every notice is checked by a person, escalation goes beyond the site itself (hosting, registrar, search engines, payment and ad networks), and support is available in the creator's language. Plans start at $69/month, and the leak scan is free with no sign-up.
ProtectFlow's answer:
OnlyFans, Fansly and Fanvue creators, webcam models, and the agencies that manage them. Many of them work in Spanish, Portuguese or Russian and prefer not to have card payments or their legal name tied to adult content.
ProtectFlow's answer:
ProtectFlow started in 2023 to help creators remove leaked content. Creators kept asking for two things the market didn't give them: someone who actually reviews each case instead of a fully automated tool, and support in their own language. ProtectFlow was built around that: AI does the heavy lifting, people make the decisions.
