Why can I send a message after deleting someone else?

Caused by the wrong permission setting.

When many users use WeChat, they find that they have obviously deleted each other, but they can still send messages to themselves. This is a question of permission setting. Wechat's friend relationship is complicated, which can be divided into one-way friend relationship, two-way friend relationship, stranger relationship and blacklist relationship. When the user unilaterally deletes the other party, it belongs to a stranger relationship, but because the other party has not deleted himself, it is a one-way friend relationship with himself.

If your WeChat permission "Need to verify when adding me as a friend" is turned off, even if you delete the other person, the other person can send a message to himself. As long as you open it, you can prevent the other party from sending messages to yourself.

The early version of WeChat also had a function called "Allow strangers to send messages to themselves". When users open it, strangers can send messages to themselves, but later with the iteration of the version, this function is cancelled.

Precautions for deleting WeChat friends

If we confirm that we need to delete friends, then we need to consider the consequences of deleting friends. After deleting friends, the other party will not be able to keep in touch with us, and we will not be able to check the other party's circle of friends and chat history. However, we need to note that deleting friends will not make the other party disappear automatically, and the other party can still see our circle of friends and chat records on WeChat.

When deleting friends, we can choose two ways: deleting and blacking out. Deleting means deleting the other person from your friend list, but the other person can still search for our micro signal and nickname. Black screen means that the other party is blacklisted, and the other party will not be able to search for our micro-signals and nicknames, and we will not be able to search for the other party's micro-signals and nicknames.
