BlockHost Ignore vsftpd

i see this in my /var/log/blockhosts.log

Warning: ignoring positional arguments - there should be none! [' --echo', '62.219.164.68-vsftpd@77.70.5.130']

he not want to block this ip , but this ip have more of 10 records failed login into vsftpd in my /var/log/auth.log

can somebody help?

maybe a backslash character in command?

As we exchanged in email, that is a warning (so can be safely ignored), but that warning is most likely caused by a misplaced backslash character in front of --echo, so if you remove that backslash character, the command will work fine.
change:
\ --echo
to just
--echo

The backslash character is only to be used for continuation lines - denoted by ending the previous line with the backslash character.
