Some times, you have to protect your community from bad people.As an instance administrator, you can choose to disallow federation for the livechat plugin.If remote actors behave badly, streamers, moderators and administrators can ban or mute users.
You can also plug in any other XMPP chat bot, using [XMPP External Components](https://prosody.im/doc/components).To do so, you just have to configure External Components access in the [plugin settings](/peertube-plugin-livechat/documentation/admin/settings).
When using software as [OBS](https://obsproject.com) for you livestream, you can embed the chat in the video stream.This is for example useful for replays.
In the following screenshot, you can see an OBS setup, where the chat is included as a source in the current scene (background color can be changed, and can be transparent):
You can even activate the chat for specific VOD videos.This is how the [demo](https://www.yiny.org/w/399a8d13-d4cf-4ef2-b843-98530a8ccbae) page works: it is not a livestream, but I have activated the chat specifically for this video.
