As a streamer, you can block viewers when you do not want them to be able to chat in your channel. To block a viewer, follow these steps:
- Select the viewer's mini-profile (By tapping their name in the chat)
- Tap the (!) symbol in the top-right corner of the mini-profile
- Select Block
Blocking a viewer make that viewer not able to chat in your channel. This will be permanent. If you wish to allow that viewer to chat again, you can unblock them in your Settings in your User Profile. If you want to mute a user temporarily, you can use the mute option instead of block.
