One issue with streaming/youtubers in particular is that you can get all of that fun-social-fuzzy feeling without actually participating and forming a real connection, it's different to other online communities in that way. Unless you dive deep into their community you don't actually know the streamers and they don't know you. You come out the other-side of a binge with nothing.

If you've got a robust social network then it's not all that harmful, and if you don't then it's at least something, but you can trick yourself into thinking that something is enough when really it can be quite a shallow and ephemeral social experience.
