To be honest I don't know what you expect to happen because I usually kick people who aren't speaking English. Once they rejoin and ask why I've kicked them and I explain it's because they're not speaking English then they usually speak English. If they don't then they're maybe kicked for a 2nd time, or banned, but it depends how quickly they decide to ignore what I've said or refuse to speak English.
We'll just input them into the system for a 12 hour ban, just in case they're active again tonight at the same time.
Ban will expire at 12 midnight.
