Why does my Visitors List show that someone chatted with me, but I haven't received any messages?

The tip "chatted with you" in your visitor list means that you have at least one chat record with this user, even if you two only have one "wave" sticker chat from a long long time ago, it can also be considered as "chatted before". It means a user you chatted with before has viewed your profile but it doesn’t mean the user sends you a new message.
