Yes, I think so.
Also, for some people, they don't want to have to discuss what happened. It's awkward. It's embarrassing. There's a component to it sometimes where the person feels shame or guilt. It's something that people are uncomfortable talking about. If you're the victim or the target of the harassment, it might be easier to try to cope with it by talking to your friends or ignoring it, because that way it's not as awkward for you as having to discuss it.
There's one thing I would like to say that I forgot to mention earlier about the person that they're reporting to. There should always be the option of reporting to a woman, because if they have to report to a man, that is more of a disincentive for some people. They don't want to talk about this behaviour with a man. They'd rather talk about it with a woman.
