That's an archetypal abusive relationship

Not all relationship/interactions with social media will be positive or neutral. Everybody knows about social media addiction already, for example. The analogy of abusive relationship IRL with various web dark patterns seems new.

Its interesting to contemplate if entirely new mental illnesses will eventually be discovered via toxic social media sites. I mean entirely new modes of dysfunction not merely "it used to be rare".

By design though, like most mass media sites.
