website design? rape survivor comms?

can somebody come onto this post or my inbox and talk about how communities for survivors of violence (sexual/otherwise) are structured? and if you had the ability to design a community for survivors, what would you really want? what features are indispensable and which ones would be amazing to have? I'm working on a website for refugees to connect with other refugees (please ask me about it) and I'm trying to look at the closest analogues that I know of that have established communities - I'm also looking at reddit subs for abuse survivors. I want to know what makes these spaces work, and I want to know how to make them as easy to work with as possible. everything you can give me, please.
