Yes, basically. Some people like throwing the term out accusatorily as if it's negative or disturbing, but it literally is just a term to describe the way social media works. Just like any 'relationship' with a person, there are good, bad, and unstable versions. For example, young people often have unstable parasocial relationships with online personalities because they're unstable pubescent fools (as most of us were) and cannot differenciate properly
Just being a fan and wanting to know normal and public information about a personality isn't unhinged at all, it's just a normal parasocial fan relationship
