I don’t disagree with the sentiment, but it will become impossible to accomplish, practically speaking, as the fediverse grows. There’s only so much that can be done with volunteers, and it’s not like armies of paid staffers work much better (as we’ve seen the major tech corps try to do).
There is a sociological aspect to this, numerous studies have confirmed the effects of highlighting bad actors. There’s a copycat effect (as studies on mass shootings show) as well as what we call the Streisand effect. Both inadvertently encourage others to perpetuate the behaviour rather than serving to limit it.
