You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows
Public reporting from Have I Been Pwned confirms the breach affected approximately 1.1 million unique email addresses. The dataset also contained real names, forum posts, and the complete text of AI prompts submitted by users. The exposure allows anyone with the leaked file to directly link a person’s email address and name to the specific prompts they used on the service. No evidence has surfaced that payment information or passwords were taken. The company has not issued a detailed public statement on how the breach occurred or when it was first discovered.
Why This Matters for You and Your Family
If you or anyone in your household ever used KomikoAI, your name and email are now tied to whatever creative or personal ideas you typed into the AI tool. Those prompts can reveal hobbies, humor, political views, or even sensitive personal situations. Once that connection exists, it becomes easier for others to build a profile of you that can be used for identity theft, targeted scams, or harassment. Children who used the platform with a family email are also at risk; their names and playful or experimental prompts are now public. The breach turns something that felt like private creative play into permanently searchable data.
The Doxxing and Identity-Chain Risk
The real danger lies in how this data chains with other leaks. An attacker who finds your email and name attached to a distinctive AI prompt can search for the same email on gaming platforms, social media, or shopping sites. That single thread often leads to usernames, approximate locations, and eventually full doxxing. Prompts that mention family members, pets, schools, or neighborhoods make the chain move faster. Available reporting describes similar incidents where seemingly harmless creative data became the starting point for sustained harassment campaigns.
