Can Qq members see other people's space and chat without leaving a trace? I know yellow diamonds can. Can I become a qq member? Nobody knows. Some people just stay and chat.

It has nothing to do with members and yellow diamonds. When you say yellow diamond deletes records, you mean deleting access records, not browsing and talking about records! Answer the question: people say that if you don't click, you won't appear in other people's space, that is, you won't add popularity to others, but you will have a browsing record because you read it.
