[intended]

Because this is not a code problem.

It is inherently a people problem.

The issue is simply that any fix (by code or by competition), will only move the conflict point from its current location to a new place on the board.

Without being able to approach the bad actors and their motivations/incentives directly, you will not be able to effect change.

And there is always going to be an incentive to manipulate minds, easily and at scale.
