That would be an incredibly bad argument. Because it’s not a motive, it’s just descriptive. “we’re at the top so we have the right” it’s just a claim we make for ourself without considering how we got there… and what if a smarter, more advanced alien race would come down to earth and conquer us? Would they agree that since they are top of the chain now they have “the right” to slaughter us? Obviously not. So then we would claim: “we’re smart! Look, we know math. And love… we also feel pain.”. So these are important to us.
One way is to just browse your home feed and make sure you selected Subscribed or similar, here look at my screenshot: https://feddit.it/pictrs/image/55638b46-9172-43b9-9ec1-65831c92fbd3.webp. Also Lemmy.World is having some issues scaling so not the best choice IMHO for the main instance, bc it would be best a smaller and stabler one.
I confirm that in the terms and condition they discourage the use as a private cloud backup and only to host stuff related to the website. Now… until now I’ve had no complaints as I’ve been paying and kept the traffic at minimum. I guess I’ll have to switch to some more cloud oriented version if I keep expanding. But it’s worked for now !
Illegal content… well it depends. Illegal informations and piracy tricks? Already happening. But beyond that… illegal medias need to be stored and at large somewhere. It’s still better to do illegal shit on WhatsApp or Telegram (as it still happens) because messages, unlike here, are end to end private. I don’t think this is so novel, it isn’t in fact, that authorities or admins don’t know what to do. Also illegal is too generic. Laws vary from country to country as well. I don’t see Lemmy becoming any sort of terrorist hub anytime soon.
If you don’t explicitly set a DNS to allow access from outside the local network, all your stuff is private and confined within your local network. As it is with all, let’s say, wifi stuff that goes on in your home.
