You can see in the snippet I added that I do have tags capability. But the messages of “banned by” are added automatically now. At least for me while using twitch website. This is sure a new addition. At least I think so. Also same message is passed for unbanning:
I tried it without BTTV and these messages weren’t showing up. I was getting regular “Was banned” message. So it seems it’s a BTTV addition? But how does that work then? I don’t see any messages being passed in IRC that would indicate who banned who without them actually giving a reason.
