I think we all agree that a good and easy reporting system and an honest and investigation system should be implemented. (Exact or Similar like the Mishpacha recommends)
You keep saying this, but in the context of the article, Rabbi Lopiansky was explaining how difficult - neigh impossible - it would be to implement such a system. There's no good answer. "Go to the authorities" isn't a great answer either. it varies by location, but most don't have the best track record. Contrary to what you might think, the issue is not that they would over-zealously charge, but that allegations would get caught up for years in endless investigations, and abusers who should be removed from their positions might not be because the authorities don't have enough evidence. Even so, most rabonim still advise going to the authorities, as they are trained and equipped to deal with this, batei din, for the most part, are not.
The primary thing that needs to be done, as every expert has repeated again and again, is to believe. Validate and believe survivors. That's it. As community members, as individuals, we don't have to get involved in the systems of investigation. We have to make sure that both in our personal lives and in the "talk" in the community, survivors feel safe, trusted, believed, and validated. You are making every effort to do the exact opposite. Think how painful that is for a survivor to read.
