Creating a system of bans for a specific user is important for chats. Since a person is a social being, he can communicate in different chats. And there may be a different contingent. And it happens that you do not want to read messages from a certain user/do not want to. This is not an insult, but closer to stalking and abuse. I would like to get not only a ban system through the BOS, but also a global ban system in chats. In practice, this may look like. The username sent the message "read" -but the message itself will not be visible
