Block users in chatrooms
I cannot find this feature, so I suppose that it's not implemented yet. I think there should be an option available that normal users should be able to block other users in a chat room. Because moderators are not always available (because they are human) normal users should be able to block persons so that they do not receive messages from them in the room. Currently normal users can block other users via the 1-on-1 chat only, but if they enter a chat room then they are still able to see messages posted by the blocked user.
