I have a feeling that this has something to do with the API not querying the database which stores the contents of the channels, the records of the channels themselves, etc, as a form of risk prevention. My thought process is along the lines of the CLI tool being allowed to query the database, as it is implied that you are supposed to be accessing the system if you are able to access the machine running the instance to use the CLI. However, for security’s sake, I would not be surprised if the API didn’t delete the information (channels, messages, etc) entirely to prevent abuse if that makes any sense. I’ll look into it and see if I can find any documentation on it.
