Tech companies hate citing the actual TOS violations because if they did, people might follow them to the letter and then the tech company wouldn't have a justification to ban them. They love having a system where they can arbitrarily declare anything and anyone to be in violation of the terms of service and not have to back it up with an actual citation. Some on HN in that past have said this is ok because people who are bad can figure out ways to abide by the terms of service while also still being bad people, so the arbitrary nature of enforcement is a feature, not a bug.
