To moderate your chat while doing a Live, you must go to the Booyah app! (it cannot be on the quick access screen of the chat, you must go to Booyah itself!) and press the name of the person you want to moderate.
Booyah! there are several ways to moderate your live, some of them are:
1- Silencing a user will prohibit him from sending messages for 10 minutes. This is a good choice for those viewers who are very "excited", but who normally do not cause problems!
2- Banning a user will prevent you from sending messages forever!
But don't worry, if you regret it or want to give it a second chance, you can remove the suspension.
Since moderating the broadcast can be quite laborious and disrupt your experience during the game, you can choose some trusted moderators who will do it for you. To promote someone to a moderator, simply press the person's name in the chat, and then select the "add as moderator" option.
