You find someone interesting on Instagram (or Tinder/happn/Bumble if they left their IG handle there), though their profile is restricted. You add that person, which accepts you, sometimes after two or three months. You leave a private message to that person, thanking it for accepting you as a follower, and asking if it wants to talk. Then, silence. Or worse yet, exchanges a few phrases and then ghosts you out of nowhere, without explanation or if you didn't said anything rude.
