In my opinion, and I feel many other people's opinion as well, the fediverse needs a place for NSFW! A place run ethically while also allowing people to (within reason) explore their kinks, sexuality, etc. as they please.
I agree that it is important to have a place for nsfw that is not full of furries or underage anime girls.
Thanks! Putting everything into a VM is actually a nice idea. Then I would just need to encrypt the hard disk file of that VM, and things should be simple. It creates a larger file though, but that is probably manageable.
There's already a furry instance, so no need to make another one.
