It's common for protocols to disconnect clients that don't behave. I occasionally see (probably automated) attempts to connect to the FTP server and then the client sends data for a completely different protocol. This can go on for quite a while and will fill up the log file quickly. I suggest adding an option that allows the user to define the maximum number of invalid commands until a connection is dropped. This might be extended to ""useless"" commands. A client can spam ""HELP"" right now to get a disproportional large answer from the server, which could be leveraged into DDoS attacks."
