+# Email Scam Detection Heuristic
 
 This application is vibe coded based on spam data. I've had a fight with a 'hacker' and since then it bombards my repository server with fake accounts. I exported this data to AI to recognize patterns and it found some. I translated that to code with safety margin. Then, I've added tests and calculated accuracy. This is good for now.
