Hey, since you said that you'd like to be more supportive:
If you have an audience, you can write about it to them. Make a post, share it with other people on other platforms, etc...
You don't have to share the link to or mention vkc, they probably have enough exposition already.
If you haven't tried this already, you can also try to pay attention on purpose for a few days in public spaces or workspaces, if you look for it, you'll see people staring and commenting poorly at women. Don't react straight away (unless you know how to) but it might help see the problems and know when and how they do it.
