"setban \"subnet\" \"add|remove\" (bantime) (absolute)\n"
"\nAttempts to add or remove an IP/Subnet from the banned list.\n"
"\nArguments:\n"
"1. \"subnet\" (string, required) The IP/Subnet (see getpeerinfo for nodes IP) with an optional netmask (default is /32 = single IP)\n"
"2. \"command\" (string, required) 'add' to add an IP/Subnet to the list, 'remove' to remove an IP/Subnet from the list\n"
"3. \"bantime\" (numeric, optional) time in seconds how long (or until when if [absolute] is set) the IP is banned (0 or empty means using the default time of 24h which can also be overwritten by the -bantime startup argument)\n"
"4. \"absolute\" (boolean, optional) If set, the bantime must be an absolute timestamp in seconds since epoch (Jan 1 1970 GMT)\n"
