There is a categorical difference with your examples for "phantom increase due to reporting". On one side it's something done to you/someone, in particular a serious crime, on the other side it's something about you/someone, in particular not a crime. This is important, because the risk of getting caught, not necessarily severity of punishment, is the main factor in crime deterrence, as far as I know. I presume, increased vigilance and ease/encouragement of reporting has a significant deterring effect on potential perpetrators. As with all sexual abuse, the vast majority of cases happens in settings where the victim knows/trusts the abuser beforehand, therefore conviction entirely depends on the victim's willingness, prospect and ability to name/accuse the abuser. Coming with the reporting, there is probably also greater awareness and knowledge about the manipulation tactics and situations enabling abuse, helping guardians, friends and authorities to identify concerning dynamics and encounters. However, I presume, the increased ease of reporting and awareness also indirectly prevents further abuse by subsequently encouraging victims to seek help and work with their trauma. I've heard a significant share of perpetrators have been victims of abuse themselves in the past, so seeking therapy after being victimized may also break the cycle of violence.
