How does WeChat want to know if the other party has blacked me out? After adding him to the group chat, delete him. Will he know?

I will answer these two questions separately.

1. Did the other party hack you? Copy a blessing message (or other irrelevant information) and send it to the other party. If the message has been sent but rejected by the other party, it means that the other party has hacked you. If the other party is not your friend, you need to verify and send a message, indicating that the other party has deleted you from his friend, but it has not been blacked out.

2. After adding him to the group chat, delete him: If you are in the same group and then delete the other person from the friend list, the other person will not know unless one day the other person wants to talk to you alone (similarly). If you quit the WeChat group, the other party doesn't know.

Satisfied, please adopt, pure hand. .
