VPN, Tor (and similar, like I2P), every imaginable P2P network, proxies, all non-http protocols (smtp, ftp, nntp, xmpp and other instant messengers and so on) can all transfer any kind of data, porn included. And a ton of other things. Heck, I’m quite sure there’s a minecraft mod where you can assemble JPG-images out of the blocks and view them that way. And then you can use stuff like uuencode where you can use anything that can move plain text to transfer binary data.
There’s no way to block all of that unless you shut the whole internet down. And even then you can still trade good old playboy-magazines with your friends. VPN in itself has very little to do with the actual problem, beyond that someone apparently noticed that their current “save-the-children” iteration had pretty large holes in it.
Do we start to build our own DNS servers too, now? I mean, not just the pihole everyone and their dog are running on local network, but independently ran network of trustworthy (whatever that might be, I’m not quite sure) DNS servers for anyone to use.
Here in Finland operators are legally in a pretty good place right now, but who knows when that might change on todays world. My own network uses root servers, but it’s still traditional DNS and prone to MITM attacks, specially from operator level. So far that’s been quite enough for my needs but on this echo chamber (of sorts) which Lemmy provides it feels more and more like I should start to harden and secure my stuff better.
