1. When a friend blacklists the other party, the friend is still displayed in the other party's address book list. After the other party opens the friend's "personal photo album", only one horizontal line can be seen under the friend's avatar and nickname. When friends change their avatars, the other party can still see their changed avatars.
When the other party sends a message to a friend, a red warning symbol will appear on the left side of the message, and the message "Message sent but rejected by the other party" will be displayed below. When you click on "Video Chat" or "Voice Chat" in "Video Chat" on WeChat, the message "The other party has blacklisted you and cannot video chat" or "The other party has blacklisted you and cannot voice chat" will appear. You need to click OK to return.
2. When a friend blacklists the other party, the other party will not be displayed in the friend's address book list, but the friend will open "I-Settings-Privacy-Address Book Blacklist" in turn on WeChat to enter the blacklist list, and click the nickname of the other party to open the other party's "Details", where you can see the other party's head. At the same time, when the other party changes the avatar, friends can still see the changed avatar, and friends are in the other party's "details".
If the other person has set privacy: I-Settings-Privacy-Turn off "Allow strangers to view ten photos", friends can only see a horizontal line under the other person's head and nickname after opening their personal photo album. If the other person turns on "Allow strangers to view ten photos", friends can view up to ten photos in the other person's personal album.
