Why did qq add a person, and when sending a message, it also said that the sending failed. Please add the other party first.

In this case, usually the other party unilaterally deleted the contact, and you need to add friends to send a message. If you are blacked out, you can't add friends. Unless you pull a black man and restore his friend from the blacklist, the black man on the blacklist will be released.

After 1.qq is blacklisted, the other party will appear in his own blacklist, and he will completely disappear from the other party's friend list;

2. The other party can't see the status of the other party (online, offline, etc.). ); Messages sent by the other party will be automatically blocked and will not be received;

3. The other party can view the basic information of friends, including updated dynamic information (such as QQ space log update, because QQ space and QQ are independent);

4. When adding QQ friends, the verification information sent by the other party will be automatically blocked for those who are blacked out. Only after the other party is deleted from the blacklist can you see the verification information sent by the other party.

Extended data

After being blacklisted by the other party, if the other party's QQ space has visitor rights, it cannot be accessed (because it is no longer a friend relationship). In addition, after successfully entering the other party's QQ space, the access records will not be left in "Recent Visitors", but the records of accessing the photo albums and logs before hacking will be kept.

QQ blacklist is used to store some harassers, annoying people and so on. Blacklist can keep you from being disturbed by someone forever. After adding the other person to the blacklist, you can't send messages or request to add friends unless you remove the other person from the blacklist.
