Hater.

An elusive hater wages a destructive game behind the guise of anonymity. Their provocations gradually draw a wide range of people into conflict—from public figures to ordinary users. Online bullying extends beyond the virtual space and begins to impact real-life lives, destroying relationships, careers, and trust between people. While those around them try to understand who is behind this torrent of aggression, it becomes clear that exposing this person could have unexpected consequences for everyone.
