The deleted person can apply for adding the other party again; When the blacked-out person adds another person, the system will automatically refuse, that is, the blacked-out person cannot be added unless the other party actively pulls you out of the blacklist. After blackmailing a person, as long as you pull it out again, you can restore friendship. If you delete it, you have to add it again. If the other party deletes you, there will be a hint. If he doesn't delete it, you won't be prompted, and he won't know. Therefore, it is easier to restore black friends than to delete them, so consider it clearly.
No matter whether it is blacked out or deleted, we can't see each other's circle of friends, we can't see it when we enter the circle of friends, and we can't see the updates, but personalized signatures don't affect it. ?
