2chan was full of trolls, so 4chan was needed. then 4chan had to go, and 8chan was born, then declared too "Qanon" and then there was other places for people who aren't liked by others and feel the same.

Persecution and suppression of beliefs we disagree with only makes for a harder, more cohesive community among those holding them. We keep discovering this anew and doubling down on failed tactics to deal with the worsening problem.

Almost as if the stated goal (no more trolls!) wasn't the actual goal.
