You'll never be 100% sure they won't get removed. Not your server, not your files.

I agree with that yet people swear on ipfs even though it's not yours. Also worse they didn't remove it I just logged in. They shadow banned it.
When you look at my page not signed in.

I'm signed in now!

There it is!
Lame. Yeah IPFS never made sense to me. Self hosting is your best bet.
Do you have a Start9 or Umbrel or other plug and play node?
No I do not have those web based requires internet in order to even use operating systems.
Huh? You could only access the internet archive using the web too...
That's not an os : ) but I get you buy a raspberry pi, find a cheap host then use their app store to find a file hosting soft to host. Man that's a lot we need to reinvent the way hosting operates. It should be much cheaper then what it is now.
Or use a computer you already have. I use copyparty to serve files from a laptop. Could expose over Tor or reverse proxy to cheap VPS.
