Write an anonymous blog about it on Medium or whatever and submit it to HN, you'll get views. You'll persuade or not persuade some people in the blog's truth no matter what you say from confirmation bias alone (e.g. rise in sexism in tech vs. rise in hoax charges). Some people will be more persuaded if you use your real name, for others it doesn't matter. Some people will be more persuaded if you give actual specifics about what was said and done (I'm one of those -- "harassment" is very broad, "groping" might be too, you need to either define your terms or state physically what happened, because you'd think we would all agree on what "grope" means but there are videos you can find of women screaming "help, he's raping me!" when it's just a cop using force to arrest her), but on the other hand too specific and people might find it literally incredible that someone actually grabbed you by the pussy without a tape of the person admitting as much.
