When you add someone to the blacklist, in your opinion, he is on the blacklist; In his QQ, your number will not disappear, he can see that you are online, but when he sends you a message, it will be intercepted by the QQ background database, and the sending is unsuccessful. QQ doesn't prompt you, but you can't get the message from him. In the QQ background database, you no longer exist in his friend list, so you will never receive the message he gave you. If his number is offline and online again, your number is not among his friends (QQ version 09 has been tried), and you two are strangers, but you won't receive the message he sent you. If you delete your friend, but you are still in his QQ, the message he sends you will appear among your strangers. You can drag him to the blacklist directly, and you in his QQ number will be deleted from the QQ background database accordingly. Blacklist can keep you from being disturbed by someone forever. After adding a friend or stranger to the blacklist, he can't send you a message, nor can he send you a message to add him as a friend unless you delete him from the blacklist. If you drag a person into my QQ blacklist, in his view, you are his QQ Qzone friend. He can check your QQ information and see your updates (such as QQ diary updates), but the other party can't contact you. For the above reasons, you must be careful when you plan to blacklist your friends.
Features after blacklisting:
1. Take a photo with her on the QQ show. If you can take a photo, don't delete it. If it's not your friend who pops up, delete it. 2. If you are blacklisted, because the QQ friend list has not been updated, the other party's QQ number is still in the friend list. When you are not invisible, right-click to select online invisibility; Or choose to be invisible when you are invisible, and the system will tell you that you don't have this friend. 3. In the group, if you add the other party, you can see it online, but if you post in the group, you can't see the other party, and the system will automatically block it. 4. Enter your QQ email address, and you can also see it in your contacts. If your friend deletes you, there will be no contacts in your contacts. 5. After being blacklisted, if the other party's QQ space has the permission to set friends to log in, you can't get in, because you are no longer friends.
