Nightbot chatfilter

Hey… My favourite Broadcaster want to prepare his channel of chatbots. Someone talked to me and said that he can use the Nightbot to filter the messages in the Twitch chat. We dont know how to activate the “verified email follower” chat. I mean just user with verified emails can write commands. I dont know how to contact in german so if you can please answer me in german. If not, contact me about my twitch account please. btw: if we can filter the follows too like the same way than the commands, that would be really nice! Thanks for help and reading this question. Have a nice day!

Nightbot does not have a “follower” userlevel, sorry.
