I had a lot of female friends growing up, and ended up privy to some details on harassment that they got. What I learned from it is that effectively 100% of women (or damn near it) have been harassed, groped, some sort of highly inappropriate behavior at some point in their lives, and especially careers. Most of the time, it goes unreported, all the way up to some fairly horrific rape events, I seem to recall hearing a number around 78% of events go unreported, which I would believe. I would always encourage them to report what happened, but they never did. To many teenage girls the idea of getting put on the stand and required to give some very graphical descriptions of acts that occurred is beyond terrifying. Many people aren't comfortable even talking about their own body parts or sex in general. Then many female adults have fears of losing their jobs if they make a report. Would it be illegal to fire them for that? Of course. Doesn't change the fact that it could/would happen and potentially make it harder to get hired elsewhere. What should be and what are are often two different things.
It's good to see these reports coming out (albeit too late) and I hope that this represents a positive change in society. That said, good people shouldn't be afraid of illegitimate reports being made, and that does occur.
