Unknown 'error'

This error (presuming it’s an error) is appearing

Usage: banid < minutes > < userid | uniqueid > { kick }

Should I worry about this? What is it caused by? Should it be there?
I’ve asked Google but it has failed me so I’ve resorted to Facepunch. Thanks in advance for any given help! :slight_smile:

Looks like some addon that runs the console command banid is not doing its job well.
