"Your IP address has been banned"

Just tried to play Assault Cube for what I think was the first time in like literally a year.
Public library, says banned which I'm guessing is a generic error message?

IP 156.110.82.222

I don't think anyone else on this IP plays since the computers can't run .exe installers (I install from .zip on flash drive)

What gives?
