I built picxstudio.com, an AI image generator. Got $850 in revenue. Then users started abusing it for NSFW content. The problem started 3 years ago with my first image gen app. Used Stable Diffusion with ComfyUI on Azure GPU VMs. Users from Asia uploaded photos of women trying to generate nude images. I tried every safeguard. They jailbroke all of them. I shut it down. This year I tried again. Used Replicate and Fal AI instead of self-hosting. Built proper UI. Used Nano Banana model for headshots and viral images. Small team curating prompts. Started getting traction. Same problem came back. NSFW abuse. What I tried: Content moderation APIs. Users found edge cases. Banned keywords. They used synonyms. Removed free tier. They paid anyway. Manual review. Doesn't scale. The truth is B2C image generation attracts the wrong crowd. The product wasn't the problem. The market was. Now pivoting to B2B. Businesses want product photos, branded visuals, AI headshots. They don't upload random photos of women. What we're building different: Brand Kit: save your brand URL, we extract logo/colors/fonts, every image stays on-brand 4 Variations: generate using GPT, Claude, Gemini, Mistral. Each has unique strengths. Team workspace without per-seat pricing No monthly subscription. Pay for credits, not monthly fees. Questions for HN: Anyone dealt with NSFW abuse in consumer products? How did you handle it? Anyone did B2C to B2B pivot? What worked? Any content moderation tools I'm missing? If you failed at something I'm about to try, I want to hear it.
