I haven’t had any problems.

The way I understand it is that communities aren’t cached (if that’s the right word) on your server until someone directly searches for it.

I still don’t really get how it all works but in my experience the only place I see NSFW content is when I look at All. I’m not sure many/any people that are registered to different instances, where they can post NSFW content, are going to see something that is posted in sh.itjust.works main.

I thought porn communities weren’t allowed here.
