There's no need to be so arsey.
I'm really sorry that you were assaulted. It must have been a horrible experience.
But, even though you have had a very bad experience, and know others who were involved, it's very clear that many of us haven't had similar personal experiences, don't know of anyone who has had similar experiences and haven't had these incidents cropping up in our social media feeds.
I think, as you're talking about hundreds of victims it's perfectly reasonable for other posters to ask for evidence, data etc.
(Edited to rephrase the last sentence for clarity).
