1. "isop" not reliable command for twitch.
2. if you are using bot to ban, why do you need person to be op? use some %variable with list of nicks who arent OPs but can use bot to ban (which IS reliable)
3. absolutly no idea what "sparta" is talking about and what is the difference with "#" and "$chan" in that case.
