Depending on the channel type your users are chatting in, they are given different labels as well as access to different actions and information. Users can interact with other users in a private chat or block specific users from sending direct messages. In some cases, users can be given an operator role and the designated operators can moderate other users who commit abnormal activities.
User vs. Participant vs. Member
Scope: Open channels
Scope: Group channels
Block other users
A user can block other users within your Sendbird application to stop receiving messages from them in 1-to-1 group channels and notifications of their messages in 1-to-N group channels. You can choose whether or not users can view which users they have blocked in the channel UI.
Note: In the Block and unblock other users section, you can see more detailed information about the two blocking modes which a Sendbird application provides.
You can assign operators in each channel to moderate participants or members with abnormal activities by banning or muting them in the channel.
The banned participants or members will be kicked out of the channel. After the ban time set by the operators expires, they can participate back in or rejoin the channel. On the other hand, the muted participants or members are allowed to stay in the channel and view the messages, but can't talk until the operators unmute them.
