Does anyone know why vsftpd would be logging to syslog even though logging is disabled in vsftpd?

First, I know we shouldn't use the built-in FTP server (vsftpd) because of security reasons but I actually added an enhancement that addresses those security risks. I'm waiting for them to merge my pull request (https://github.com/limetech/webgui/pull/958) into the codebase but until then I am using it.

I have all logging disabled in /etc/vsftpd but for some reason it is still logging to /var/log/syslog and I can't figure out why.
