Snapchat profile cannot be found but keeps taking screenshots of mine?

Hi everyone, a while ago, a Snapchat account started taking screenshots of my profile. At that time, I could also see her profile. After that, I could still see her profile from our conversation, but her picture disappeared, and neither I nor anyone else could find her profile. I thought the profile was deleted, but she keeps taking screenshots of mine, which means it's still in use. What's wrong with that? I still can't see the picture and the profile can't be found using the username.
