I often post fair-use homework questions that are explicitly allowed for reproduction. Sometimes a question is harder, and takes longer to answer (reasonable, right?) If the question is really hard, I get a "routine audit" of my account saying that I posted copyrighted material. I know for a fact the material is fair-use, so they literally gave me "copyright strikes" every time I posted a question that nobody wanted to answer. They terminated my account today. I want my money back.
