So here is the story.I didnt like one of my bf’s girl follower cz she was a little more flirtatious with him. i asked him to block her he only restricted her account.But i didnt know that at the time.When i checked his followers i couldnt see her so i thought he blocked her.Then i searched her name in the search bar couldnt find her either.But today suddenly his follower number increased by 1 and i can see her in his followers list and can search her up in the search bar.He didnt gain any knew follower i also checked this.So whats happening? i thought she blocked me but she doesnt know my account.Can this be an instagram bug?
