I think that the members who report do experience retaliation and additional harassment for reporting. As for the outcomes of having a report done, people are aware that it will not be pleasant for members who report they are a victim of sexual assault.
Basically, there's no winning after you've been victimized by a sexual assault. I don't believe that you as a victim will get a good outcome from reporting, no matter what. Even if your harasser or your abuser is found guilty, it will still be a hard road to go down. It will not be a pleasant experience.
