Recently I noticed a lot of users just randomly cutting into the message walls of others. For example, my friend and I are chatting about something, a stranger suddenly interrupts. It’s not good for privacy, how can I avoid this?
So someone on my wiki was talking about his difficulties and I was trying to help him, another guy just came in. The guy became very angered and told him to get out, but I can’t block a user from viewing message walls.
