I was just banned for a while, it seems to be lifted as I was registering for an account on here however. This was the message I got:
Connection closed unexpectedly: Closing Link: Californ1a[highgate.irccloud.com] (User has been banned from GeekShed (Session limit exceeded))
I'm using IRCCloud bouncer, which is likely the reason, but really that shouldn't be an issue because they have information listed for networks on how to prevent this:
