I sent a message in qq space saying that I can only see one person, but why is that person a blocked visitor? Did he see it or not?

Hello, I'm glad to answer your question.

First of all, you need to confirm whether you are sure to allow the other person to visit your space. If you are not allowed to visit the other party, it will appear in your blocked visitors.

Another situation is that you allow the other person to visit, and the other person sees your conversation, but the other person also sees other places in your space, such as the photo album where you set the question.

The other party can block your news or news.

So you can't see it in space.

I hope I can help you.
