By “illusion” are you suggesting neither civilization nor anonymity exist? I struggle to come up with a more preposterous thought.

In both the real world and cyber communities bullies, cowards at heart, exist and prey on anyone crossing their path. They are inexcusable in both environs.

In the real world they can and do inflict physical harm and occasionally get their royal asses whipped. Here in la la land they can be ignored, shamed, ganged up upon, blocked, banned and, unfortunately, are rarely injured in the process.
